Mmm, also Felix has trouble with psaux. It's to soon to say they are
related though...

Uhm, psaux is a character device. In principle, you can open it like an
ordinary file but I guess vi stat's the file first to determine its type.
Better to look at /proc/interrupts f.i. to see if interrupts are being
caught.

IRQ 11, 10Mbit card? Mmm, can you show us lspci -v?

IRQ 5, 10M/100M/1Gbit card? Sharing with USB device! Show us ifconfig eth1
if you can get the link up...

It probably all works but it is an ugly IRQ setup, at least according
to my experience and taste :-)
We need /proc/interrupts anyway... (make sure to move the mouse a bit
after boot even if it doesn't move the cursor, we want to know if it
is a hardware/driver problem or a software problem(gpm/X).)

Anyway, if it worked before and stopped working recently, it is either :
* the mouse or the PS/2 mouse port has become flaky
* the kernel PS/2 driver changed
* isapnp changed and ISA probing is screwing up the hardware even harder
  than it was notoriously able to do before (that's why probing should be
  avoided once the resources are known and isapnp.conf is updated
  accordingly).
* the PS/2 mouse packet driver in X has changed and now contains a rarely
  tripped bug. (It is most likely adapted to the "new" XF86 4.0
  architecture but it is rather hardware independent so most people
  using PS/2 mice should have experienced this bug if there is one.)
* new hardware was recently inserted and it (or its driver) is interfering
  with the PS/2 mouse port.

This breakdown counts for everybody experiencing (PS/2) mouse problems...

PS: Maybe in some critical cases, PS/2 doesn't like cooperating through
devfs. That would be option 6...
