Dan suggests (look at the mailing list archives) that linux-2.3.18.tgz
is what you should use instead of mpc8xx-2.3.10.tgz.  He also suggested
that he might remove the mpc8xx-2.3.10.tgz archive and I think that
would be a good idea if it has problems compiling or has some confusing
elements.  Since it is a bleeding edge release you must expect
problems.  I have reverted back to the embedded-2.2.5.tgz archive for my
port.  It compiles fine with the right options.  I would probably
recommend the 2.2.5 stuff for first timers (like me) as this is the most
stable version and there are apparently lots of MPC8xx boards using this

I have had no problems compiling the kernel with the x86->ppc
cross-compiler, though I would still love to have a PowerPC machine
instead of an x86.  The only problems I had have been choosing the right
configuration options.  Once you have sorted this out you should be
fine.  Have you installed a x86-ppc cross-compiler ?  I can help you if
you are having problems with it (building the compiler or using it to
compile the kernel).  Note that any questions on building an i86->ppc
cross-compiler should be sent to the crossgcc mailing list.  See for FAQ and subscription details.  I am using
egcs-1.1.2 and there is a prebuilt egcs-1.1.1 cross-compiler available
from the LinuxPPC web pages.
