I have used it with the AT91M40xxx all the time. Are you sure that you
adapted asm/arch/hardware.h for the EB63? Most of the necessary AT91
changes can be found in the 2.0 kernel at http://cvs.home.at/. There
two separate architecure specific directories for the EB01 and the EB63.
In the 2.4 kernel, everything is in one arch-atmel directory. I think it
is better this way because the AT91 CPUs are very similar.
