Ok, I'll take a stab at those later today (and also your comment
from the other mail).

One other thing: I wasn't sure about my changes to rtl8139_get_regs
and rtl8139_get_regs_len.  Is what I did there safe?
Obviously actually implementing support for PIO reg dumping would
be better, but I think that's beyond the scope of what I'm trying
to do for now.

Yeah, that should be reasonable
