    Michael> What about 32 bit?  I see this in timex.h:

Yes, 32 bit is fine.  That stuff in timex.h is there to fix up some
sort of crazy PPC 601 stuff (and 601 is so old I don't think anyone
cares or even has a box with both PPC601 and PCI).

    Michael> Could some PPC gurus here chime up on what this does?
    Michael> Cant I just "mftb %0, 268"?

You can just do "mftb %0" to get the low 32 bits of the timebase, and
"mftbu %0" to get the high 32 bits.  I'm not sure what the ", 268"
would do.
