Can you use a newer kernel that will do all of this for you automatically?

That isn't correct with the latest BDI firmware. The address at 0xf0 is
not the address of the page table, it is an indirect pointer to an array
of page table root pointers. Later kernels will set up all of this for you.
We unfortunately had a short-lived version of kernel and BDI2000 that did
use the low address as a pointer to the kernel page tables, but this isn't
done any longer.
Thanks.
