In order for me to tune up xine's Performance, xine-check revels:

[ hint ] you have MTRR support but it's unused.
It seems like your X server didn't set any MTRR ranges for the
graphics card. Maybe upgrading your X server helps...
You don't have a PCI graphics card, do you? AFAIK, MTRR only
helps with AGP cards.
press <enter> to continue...

AFAIK, that is what I have: GeFORCE FX 52OO AGP - 128MB DDR.
SYSTEM DETAILS BELOW!

/usr/src/linux-2.4.29/Documentation/mtrr.txt This file indicates that if I
run: cat /proc/mtrr the result should be: (mtrr.txt is over my head!!!)

% cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size= 128MB: write-back, count=1
reg01: base=0x08000000 ( 128MB), size= 64MB: write-back, count=1

But this is what I get:

$ cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1

I don't have a reg01: line. And here's what I do have:

cat /var/log/Xorg.0.log | grep Linear
(--) NVIDIA(0): Linear framebuffer at 0xD8000000

cat /var/log/Xorg.0.log | grep VideoRAM
(--) NVIDIA(0): VideoRAM: 131072 kBytes

So do I have what I need to put this all together? And, if so, just how is
that done? It sounds like some math conversion is need, but using the
handy KCalc all I get is: 131072 = 20000 in hex. I'm think that maybe;
a sysctl.conf is needed? And I can't make heads or tail on the "using
ioctl()'s" part of mtrr.txt. But, maybe I don't need to?

I would appreciate any suggestions
Thank you very much

This is just an example to show you what this "file" should look like,
it does not mean you should have the same values.

Here is what I get for the same graphic card :

linuce@piteplop $ cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size= 256MB: write-back, count=1
reg01: base=0x10000000 ( 256MB), size= 128MB: write-back, count=1
reg02: base=0x18000000 ( 384MB), size= 64MB: write-back, count=1
reg03: base=0xd8000000 (3456MB), size= 128MB: write-combining, count=1
reg07: base=0xe4000000 (3648MB), size= 64MB: write-combining, count=1

> I don't have a reg01: line. And here's what I do have:

I have reg07 but I didn't have reg04, reg05 and reg06

> cat /var/log/Xorg.0.log | grep Linear

linuce@piteplop $ grep Linear /var/log/Xorg.0.log
(--) NV(0): Linear framebuffer at 0xD8000000

> cat /var/log/Xorg.0.log | grep VideoRAM

As you can see, I have 131072Kb of RAM with a linear framebuffer
address starting at 0xD8000000. So I should use these values as
reported by the X server (and as recommended by mtrr.txt) to configure
MTRR. However, if you look at my /proc/mtrr, it already contains the
"right" line (reg03). Your does not, so you should add it. From what
we can read in the mtrr.txt file, you should use a command line like
the following one :

echo base=<Base> size=<Size> type=write-combining >| /proc/mtrr

In your case, you have Base=0xD8000000 (as reported by "grep Linear
Xorg.log") and Size=0x20000 (as reported by "grep VideoRAM Xorg.log").
So, you shoud probably run the following command if you follow what is
explained in mtrr.txt :

echo base=0xD8000000 size=0x20000 type=write-combining >| /proc/mtrr

If you are unsure or if don't understand how I have built this command
line, please do NOT run it. If you run it, there is even no guaranty
it will work, you are on your own, etc.

Shot in the dark - Do you have Option "No MTRR" set in your xorg.conf?

Thanks you so mush, LiNuCe. This is what I used:

echo "base=0xD8000000 size=0x200000 type=write-combining" >| /proc/mtrr

And now:
cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1
reg01: base=0xd8000000 (3456MB), size= 2MB: write-combining, count=1

$ xine-check
[ good ] you have MTRR support and there are some ranges set.

Now I need to see how I can get the right range set and then create
type=uncachable region. So I don't have redo it after reboot.

Thank you, Old Man. Just yesterday I had put in Option "MTRR"
