Since agpgart is the last thing loaded before getting this segfault, I
completely turned off AGP, including DRI. Now it boots, but I can't load
any module: I get such a segfault too, this type, this one is taken
directly from my /var/log/messages:

I get that on any module that has no dependancy, like soundcore or
parport; those that have dependancies will only display the usual
unresolved symbols errors.
Notice that the executed Code that is responsible of the error is the same
sequence -- so that may hint that it's possible to reproduce the segfault
on other machines.
Tell me how the Call Trace works, but I think that c8010000 is the address
of the last called function, and the latest one with a symbol within is
swapper_pg_dir --> could this mean a incompatibility with the swapper
(inside the kernel) and another module? memory corruption? I haven't
investigated that a lot.
I used egcs-1.1.2 to compile the kernel. System runs RH6.1 w/ K6-2/450 and
a VIA MVP3 mobo.
A little side-note: I have no use for the AGP and DRI drivers; I'm
compiling them to be ready once nVidia releases their long-awaited high
performance drivers, and for the moment XFree86 4 comes out. I also have
no USB peripheral; I'm compiling them all to see if it still compiles fine
(2.3.39-41, I think, had one module that wouldn't compile at all. It's
fixed now).
I hope it can help.
