Sometimes while FreeBSD boots, it hangs in pmap_bootstrap in sys/powerpc/aim/machdep.c

Trying to find out why.

Investigating further.

MMU_CPU_BOOTSTRAP(mmup,0) hangs in moea64_late_bootstrap.
MMU_CPU_BOOTSTRAP points to mps3_cpu_bootstrap.

Maybe related to ps3fb_remap.

Replaced

lv1_gpu_close();
lv1_gpu_open(0);

with

lv1_gpu_context_free(0x55555555);
lv1_gpu_memory_free(0x5a5a5a5a);

And it seems that hangs are gone now. Need more testing.
