Yeap, I'm getting this too. There seems to be a whole bunch of changes 
in include/asm-ppc64/pgtable.h that aren't in include/asm-ppc/pgtable.h

This is at least my guess.
By doing the dumb cut&paste business I've gotten further along, but 
haven't done enough to actually compile fully yet. I'm half nervous 
about doing a lot of this as I have no idea about this level on ppc 
(maybe benh, the maintainer of linux for power mac could help out?).

If I get anything going, I'll let you know.

on an architectural question, there seems to be a lot of duplication 
between ppc and ppc64, should they be more closely melded or is there a 
really-good-reason(tm) behind the seperation?

I should say that after my post, I tried out the linuxppc-2.5 2.5.66
tree at http://www.penguinppc.org/dev/kernel.shtml, and it did not
have this problem.

However, I could not get it to compile for numerous other reasons:

 * If PnP BIOS is enabled, it fails to compile the x86 assembler.

 * All Modules fail to load due to some sort of missing symbol (sorry, I
   didn't take notes) Q_MODULE or something maybe.

 * A non-module-enabled kernel fails to build, complaining of a
   missing isa_virt_to_bus symbol.  And that happened even after I
   enabled the unnecessary ISA support.

 * hdparm causes a kernel oops and apparent lockup (again, I didn't
   take notes, I was just trying to make the darn thing boot)

In short, 2.5 on PowerPC does not seem to be in a very good state
right now.

Have you installed module-init-utils?
