This one seems to have been around for quite a while (2.4.0-textX ?)...when
compiling with CONFIG_MK7=y ("Athlon/Duron/K7" as Processor family) a lot of
modules aren't able to resolve the symbol _mmx_memcpy. This is caused by
CONFIG_X86_USE_3DNOW=y and the problem lies in a wrong symbol export in
arch/i386/kernel/i386_ksyms.c - I wonder why this still hasn't been fixed as
it doesn't seem like a hard thing to do for someone who's into kernel
patching...being new to that, it took me about 3 hours.
Here's the patch (it's just one line so it should work for other 2.4.x
kernels as well)
