DOSEMU is not a generic 32-bit Linux application, though -- it's using a
very specific syscall to run 16-bit applications. It's not something
emulable, and the CPU running in 64-bit mode supports 32-bit applications,
but probably doesn't support the necessary segment types and modes for VM86.

See http://dev.gentoo.org/~tester/amd64-...otes-orig.html
which specifically notes that DOSEMU won't work under AMD64

There is, however, DOSBOX, which doesn't use VM86 mode, where there's a
AMD64 RPM available (see for example
http://speakeasy.rpmfind.net/linux/RPM/Emulators.html )
