Bad 486 dumpage

[James Stark <consume@pacbell.net>]

I have an old 486 that is having issues.  It was my gateway 
for a few days until the problems just got to be too frequent.
I pulled it as the gateway, swapped a potentially skunky 3c905 
and re-installed 2.6 on her.  Anyway, it is still goin' on.

First, can anybody elaborate on what the following dump code
means (besides the fact that it probably deals with virtual memory)
Is there any particular piece of hardware that, based on the
message, is just screaming to be yanked from this poor system?

->  vm_fault(0xe0ad1a00, dead0000,3,0) -> 5
->  kernel: page fault trap, code=0
->  Stopped at _vm_page_inster+0x94:  movl  %ebx,0(%eax)

Secondly, is there a way that I can set the system to automatically
reboot when this happens again?

Thanks in advance,
James
