Ok, I disabled USB in the BIOS and checked under Linux. Linux was not
assigning an IRQ to it. Went ahead and did some board swapping, and now
there are no shared IRQs. Still no joy.

My HURD partition is on dev/hdb1. I've followed the steps in the Easy Guide
verbatim, for the tarball install. Booting GRUB from floppy.
root=(hd1,0)
kernel=/boot/gnumach.gz root=hd1s1 -s

The box is an Athlon 500, on an Asus K7M mobo. There was a problem with
linux kernel 2.0.x and Athlons. Is it possible that the MACH has the same
issue?
