Sorry for the vague subject, this problem is hard to summarize.

Bascically I'm trying to get Linux to forget what USB mass storage
devices (keychains, portable HDs, etc.) it has seen.

When I plug in a keychain it is attached as /dev/sda1 and I can do stuff
with it (mount it, use mtools, whatever). I unplug it and plug in a
different keychain. That one is attached as /dev/sdb1. And so on.
Each new USB device is attached as a different SCSI device.
/proc/scsi/usb-storage-*/* correctly shows the devices, and correctly
indicates which are still attached.

The behavior I need is for Linux to forget the device when it is detached.
If I plug something in it should show up as sda1. If I unplug it and
plug something else in the new one should show up as sda1. The only time
I want to see sdb and higher is if I have more than one device plugged in
at a time.

Is there an easy, clean (no gross automount stuff) way to do this? Or
do I have to hack the kernel?

OP, I haven't tested that myself but that seems to be the working solution.
You may want to google around and ask the hotplug gurus if there's some
way for hotplug to detect the removal of the usb drive and then remove
that module and re-insmod it, or perhaps some way to wipe the module
clean whenever the disk is removed.
