Hi all,
Alexander has been very busy with porting everything to kernel 2.6.34 which is no small feat!
I just received a tar ball containing a copy of the kernel sources and just finished a successful compilation.
As a bonus it seems Alexander has been able to get more devices working among which is the v4l interface for the on board camera!
Hopefully it won't take long to get it all into a repo on google code so that it is available for the die-hard kernel hackers among us.
We will see how this will develop and i will keep you people updated.
Best regards,
Jan Rinze.

ok, short update:
built a kernel and it boots my rootfs :-)
