Hmm, that's probably not the int10 module itself, looks more like some
mmap() failing without the error being checked or something trying to
jump to an unresolved symbol.
Funny thing is, I'm using the siliconmotion driver myself, on Gdium,
which has an SM502. The driver probably doesn't even try to use int10
on that hardware since it's got no VGA compatibility whatsoever and was
never intended to be paired with anything x86.

Yeah, I've seen that one but never got around to investigate or even
check if it still happens with 4.5

Hmm, I tried to build things on Gdium with 4.8 and patches, which
successfully built simple stuff like flops but when building things
like python the resulting binaries would crash.
On sgimips ( using an n32 userland with gcc 4.5 and the patches I sent
ast time ) I managed to get a working tcsh before failing due to other
issues. Without the patches I get the same errors as on loongson
( unsurprisingly )
I should probably try to build an o32 userland for sgimips with gcc 4.8
just to see which issues go away, if any ( the gmp crashes /should/ go
away since it should be purely 32bit )
