well, hang on. The oops said:
EIP: 0060:[<c0529da1>] Tainted: GF VLI
EFLAGS: 00010272 (220.127.116.11-85.fc13.x86_64 #1)
EIP is at do_page_fault+0x245/0x617
eax: ec5ee000 ebx: 00000000 ecx: eb5de084 edx: 0000000e
esi: 00013103 edi: ec5de0b3 ebp: 00000023 esp: ec5de024
ds: 008b es: 008b ss: 0078
which is NOT a rhel 5.0 kernel, and it says x86_64.
But the addresses are all 32 bits?
So what's going on here?

end of the stack is ec6ee000, stack grows up, esp is at ec5de024,
well past it (i.e. yes, overrun) if I remember my stack math
right... but that's a pretty huge difference so either I have it
wrong, or things are really a huge mess here.
