I managed to get it running on Triton. If you do get
stuck in switching to virtual addressing(in function
setttb()), it is because the L1 page table entries
that netbsd copies over -contain an invalid entry. The
algorithm in place copies all entries setup by the
bootloader (redboot) until it finds an invalid entry.
Since the first one is invalid, but the rest are valid
-you need to skip it and copy over the rest.
