This is still true.  However, if NetBSD is going to run on ISA
machines, it _needs_ to have this support.  Sure, it's simplier to
respond with the all to common ``buy better machines'' but the point
is, there are a _lot_ of DMA mastering cards out there, and they
_need_ to be supported.

If memory serves, OS/2 doesn't support this > 16M, and I think even
Adaptec's drivers are documented not to work past 16M.  At least some
flavors of them.

BEEP!  They're in the pr database.  Query it.

The changes are to more than just the 1542 code.  It changes some of
the isa dma code, and the changes would quite likely break the amiga
and alpha ports right off.

I have heard Chris has the bounce buffer support on his TODO list.
How about we give him time to work on it, so it's done right?
