for the particular card in use. At the moment, I've set it to any of
the bt445S VLB cards (not the bt445C which apparently work) and the
bt5xx series (isa cards). The 742 and PCI cards should not need it. :-)
It may be useful to have something like this:
#ifndef BOUNCE_BUFFERS
if (bounce_buffers_required && more_than_16MB_ram)
panic("this card requires bounce buffers for more than 16MB ram!")
#endif
