I spent some time digging into it and it's not trivial. It's definitely
easier if we limit ourselves to a 32 bits host kernel, but then, I don't
intend to support 32 bits kernels indefinitely on the G5. Havign the
module work within a 64 bits kernel is definitely more difficult. There
is some work beeing done here by Paulus rewriting the ppc64 kernel
exception entry/exit path, I'm mostly waiting for that to be done (and
other stuffs eating my spare time) before I have a look at it again.
