ML403 Linux port questions

I am using an AMCC PPC405EP based system and find that the following
Development / build machine --> Fedora core 6 or 7 on x86 PC
Cross compile and target rootfs generation --> Buildroot
Linux kernel (at least to start with) --> 18.104.22.168 from DENX ELDK 4.1
Of course, you can use the cross compile environment from ELDK if you
like. I used it at first (had a very good out-of-box experience on AMCC
Taihu with it) and then switched to Buildroot later.

I am presently using the Linux 22.214.171.124 kernel with I-Pipe real time
extension (2.3.0) from the Xenomai project - as bundled in ELDK 4.1 by
DENX. I have also experimented with some newer stuff, but this involves
diving into the board support migration from arch/ppc to arch/powerpc
which is still pretty bleeding edge. 126.96.36.199 is pretty safe and not too
old - and is probably the newest available with RT option while still
being in the arch/ppc tree.
Don't attempt to have buildroot automatically build the kernel for you
as part of its config - that may cause you grief as their integration
for PowerPC kernels appears hit-and-miss for 40x series due to all the
arch/ppc versus arch/powerpc stuff. Also, the buildroot automatic
kernel generation doesn't include RT support (in case you need it).

Subject: ML403 Linux port questions
I'm setting up a new development environment to get a working port of
Linux on the Xilinx Virtex-4 chip (I have a Xilinx ML403 board). I'm
looking for the quickest way to get a working development environment
for the 2.6 kernel without paying thousands of $$
I guess what I am looking for is advise on the lowest risk, easiest to
set up environment to setup that will just work. Also advise on which
kernel to use.
