We have been successfully using linux Linux-2.6.32-rc8-01395-gbb09de5-
on a custom 5200 board (very simlar to Lite5200).
I got the latest linux-2.6-dex.git (Linux-2.6.34-rc7-01433-g2745a31-)
and diff/patched our board support and used the same .config; but the
command line is not received by the kernel.
We have not changed u-boot (2009.11-rc1-00017-g5822035-) and
environment variables with
bootargs=root=/dev/nfs rw nfsroot=192.168.1.103:/opt/eldk/ppc_82xx
ip=dhcp panic=1 console=ttyPSC0,115200

Maybe the 'Zone PFN ranges Normal empty' is a hint.
Any ideas?
