This is a longshot, but...

I've had this experience with a Riva (NVidia) chipset-based video card and an
ethernet card both using the same IRQ.  With X running, an ifup caused an
immediate system crash.  As far as I know, the video card and XFree driver
didn't need to use the IRQ, and /proc/interrupts showed that it was not
registered.  However, with X not running, 'ifup' did not crash the machine,
and I could get networking working. 

To check on this, 'cat /proc/pci' and check whether you've got two cards 
listing IRQ 11 as a resource (my AGP Riva card also uses IRQ 11).  If so, 
you'll have to move the GNIC II board to other PCI slots and/or play the 
usual games to try to get it assigned a different IRQ.  Or not run X at 
the same time.  I vaguely recall that there was discussion on USENET of 
an error in the SVGA server related to this interrupt.
