Well I use debian sarge (testing) for the development I am doing at
the moment on a PXA255 based board.  The compiler recomended by the
board maker is 2.95.4 (they provide a cross compiler for x86).  Their
latest patch is for 2.4.26.  I have successfully managed to make the
patch apply to debian 2.4.27 sources, and made it compile with gcc 3.3
which allowed me to change the tuning to native xscale optimizations,
which seems to have made the system somewhat faster.

I really doubt you have to use gcc 2.95.3 at all, unless any kernel
patches contain very bad assembly syntax.

I have had no problem using gcc 3.x compiled applications with 2.4.18 or
2.4.26 or 2.4.27 compiled with either gcc 2.95 or 3.3.  You should be
able to just use standard packages with whatever kernel you manage to
