I recently bought this system:
http://www.visionsystems.de/produkte/6801.html

The computer runs standard debian-arm binaries except kernel which is custom (for Mikrel KS-8695).
The system has 64MB RAM, 4MB Flash and CF interface. It uses Redboot for startup and in the beginning executes a mini-linux from internal flash (as Bios), and then, loads a new kernel from CF.
The linux kernel (2.4.32) sources are provided here:
http://svn.visionsystems.de

The output from system:

I need some help to start porting OpenWrt on this machine.
Which is the nearest supported device to start a new profile? Is NSLU2? or Generic Arm?
Any hints are welcome....
