I'm not sure where I got it, but I have a nice book on PPC assembly that gives
quite a bit of help, called "Optimizing PowerPC Code", by Gary Kacmarcik.
It's a fairly early book, but not much has changed since the PowerPC was new.
All you need to know is that the 604 and up have three integer units instead
of one.

As far as registers go, the powerPC has 32 64-bit floating-point registers
(great for blitters) and 32 32-bit general purpose registers.there are also
several special registers (machine state, link, counter, rtc (only on 601),
etc).

Does anyone know if 64-bit powerPC's ever came out (e.g. the 620)?  I noticed
that the vger kernels (I think at least the 2.3 ones) have had them for a
while now.
