That doesn't make much sense and would be a serious limitation, since
machines on their supported list can accomodate up to 64MB.

I can see problems going over 16MB on ISA bus machines, but I don't
see why 12MB would be a problem.  Does anybody know how they handle
DMA in ISA bus machines with > 16 MB?  (e.g. what they do in lieu
of AT&T's DMAABLEBUF parm).
