Funny, I was just about to ask  very similar question. I will be working
an a IBM PPC405G based development board (Cogent CSB272) for an internal
project. I would like to use as up-to-date versions of GCC, GLIBC and
Linux 2.4 kernel as possible (without sacrificing stability).

- Has anyone used recently released 2.4.23 (kernel.org) in any PPC project
yet? If it is not good to use for PPC based development? Do I need to get
a ppc specific modified kernel or do I need to apply any patches to linus
2.4.23 kernel to get it working in PPC405 embedded environment.

- Kernel 2.4.x README still says the official kernel compiler is gcc
2.95.3. Is it still the case or using a more recent GCC compiler is now
acceptable? In the last Linux embedded project I was in we had used this
one along with a very early build of kernel. I was not the one to set the
development environment so bear with me if these sound basic questions to
you.

- I built a toolchain using crosstools based on gcc 3.3.2, glibc 2.3.2 and
binutils 2.14.90.0.5. Crosstools default .dat files pull kernel 2.4.21 but
I also got the tools compiled using 2.4.23 sources. I have not tested them
yet since I don't have the board yet? Any comments regarding this
combination?

Looking at some ppc linux distros (not necessarily embedded):

YDL 3.0: kernel 2.4.20, gcc ? glibc 2.3.1, binutils ?
Mandrake: kernel 2.3.21, gcc 3.2.2, glibc, 2.3.1, binutils ?
Gentoo: kernel 2.4.22, gcc ? glibc 2.3.2?, binutils ?
