Perhaps the idea should instead be extended to sort of generic "IO
memory" - on psionw there is some memory that is used for fb (part of
it can be allocated as normal memory too provided you don't choose
4bpp). It'd be nice if (a) that memory could be used and (b) that it
would only be used as a last resort to make it easier to switch to
4bpp at runtime.

I don't like the pmap_bootstrap thing at all as it doesn't really gel
with where the kernel is loaded on psionw - there is some memory in
small patches before the kernel as well as the larger lump after it.
