I think I was able to get kdb to stop dying inside unwind_table_init.

Is this a gcc-ism we're seeing?
Note-to-self: Look at .S produced from compiling unwind.c
On another note, we have no code that calls unwind_table_add so I've
#if'd it out. Which makes me wonder... which change was the fix?
Time to go back to square one and try them out independantly.
The kernel still goes into an infinite loop of unknown origin:
PCI or EISA Bus Adapter 0 is not registered...
(see ./arch/parisc/kernel/pci.c' -> PCI_PORT_IN)
Don't know where this gets called from, or how the ugly macro
Sadly I think I zapped my VGA out on the 712/60 (A common occurence?).
It no longer produces _any_ video signals.
I may have to drag a 715/50 back to my house...
