[Barrelfish-users] Problems with the MMU and a different memory layout

we've been trying (rather unsuccessfully) to get Barrelfish up and
running on a slightly changed integratorcp board in qemu. The problem
is, we don't have memory at 0x0. Our memory starts at 0x20000000. We
changed the boot.S to reflect these changes but as soon as we enable the
mmu we get an prefetch abortion. And honestly we are running out of
ideas why this keeps happening. We stepped through the whole process in
gdb but everything seems fine.
We would be very happy if somebody could take a look at our boot.S and
point out the obvious mistake that we can't find.
Here's the link:
Thanks and cheers
