Problems with 2.6.23-rc6 on AMD Geode LX800

Hello all,
yesterday I tried to boot a kernel built from the current wireless-dev git tree (ath5k branch)
on a MSEP800/A board (see http://www.milesie.co.uk/pdf/MSEP800.pdf). The board
contains an AMD Geode LX800 CPU.
The wireless-dev tree is up to date with Linus kernel 2.6.23-rc6.

Attached is a photographic screen shot. The EIP value of c0378dd6 seems to correspond with the
reserve_bootmem_core from System.map:

c0378d51 t free_bootmem_core
c0378da7 T free_bootmem
c0378db2 T free_bootmem_node
c0378dba t reserve_bootmem_core
c0378e14 T reserve_bootmem
c0378e1f T reserve_bootmem_node

Additionally I'm sending the .config file used to compile the kernel.

Additional information:
* The last known good kernel on the MSEP800/A is 2.6.20.14
* The exact same kernel binary boots fine (well, until it tries to mount /) on a standard desktop PC with a 2.5GHz Celeron CPU.

Am I doing something stupid or is Linux currently broken on this CPU?

Thanks in advance and kind regards
Joerg
