No idea if it works or not any other than AMD64 (and i386). I use AMD64
Kernel on my computer and I cannot test easily any other arch's as I
don't have suitable hardware. i386 is so common which means bug reports
are got very quickly and fixed.
Generally speaking I am a little bit surprised these drivers seems to
just work from arch to arch quite often.
