Also, the last patch in lmb branch "ARM: use LMB to allocate system
memory MMIO resource structures" causes both osk5912 and n900
to hang very early. Maybe I'm missing some patch again..

I'll drop this patch for the time being - we don't have stuff in the
right order yet for lmb_alloc() to work immediately after arm_lmb_init()
with highmem present - lmb_alloc tries to allocate from unmapped or high
memory, which we then use __va() on and referencing the resulting pointer
causes an abort.

However, using lmb_alloc() for the OMAP framebuffers shouldn't be an
issue because the problem only happens if you want to immediately
dereference the memory.
