AFAICT, this is not a problem of finding the right patches, but to get
them accepted by Linus.

The vger cvs tree has had a compiling 2.3.3 kernel for some time (I am
running it right now). The one I am running is from last Friday, the one
checked out today compiles, but doesn't boot.

I think if you want to use 2.3.x kernels, you have to accept that these
are development kernels, and that there are periods when they don't

After all, there is the stable just one week old version 2.2.9 (although
the official 2.2.9 kernel includes this broken patch of
arch/ppc/kernel/syscalls.c that didn't come from vger).
