Hmm, is there no way to set MAXBSIZE per device basis?
Or, could anyone try the new asc driver with 64K MAXPHYS
on PICA or ImageRISCStation? ;-)

I think NCR53C94 (actually it's FAS216?) with MI ncr53c9x(4) can
handle 64K xfer even with 16bit TC regs as other ports do and
jazzio DMA has no 64K limit.
