BTW. The cset I sent you contains code from Dan Malek that implements an
elegant solution to the CPU detection stuff by emulating the "mfspr"
instruction when issued from userland. We can also (not done yet)
masquerade the CPU (by letting it think it's a G3 and not a G4 when
altivec is not enabled in the kernel for example).
