No, we have not implemented generic bounce buffers.

In short, the answer I tell everyone is that if you need more than 16MB,
get an architecture that can do it (EISA), or buy BSDI. :-)

If you NEED more than 16MB on an ISA bus, you are already in trouble,
so why not spend the extra $$ and buy an EISA machine with EISA
cards.
