Actually, I think this is best expressed by the following change that's in
my tree:

	return (m68k_trunc_page(pa) == m68k_trunc_page(mac68k_vidphys));

I made a mistake when I interpreted the comment for pmap_extract() by not
looking at the code!  I had assumed that the return value was
page-aligned, but it's obviously not.  `Oops.'

If anyone is interested in testing my changes, please contact me
privately.  (This more or less assumes you can compile a -current kernel,
as I don't have the resources to compile many custom configurations.)
