sorry for my late answer - I have been at the Embedded World for the
last week.

Kyle has already mentioned my patches - look at our homepage, I have put
my latest snapshot there, mostly as a reference until Wolfgang has found
some time for integrating it into CVS. Anyway, the memory initialisation
works here.

Didn't try this, but there have been some memory map topics (for example
ARMBoot had the stack above the relocated code, not below like stated in
the README). The .bss segment has not been initialized with 0 in the
original code which could also be a source of problems.
