This is the way it was until recently. This was changed because it
requires the driver-programmer to know the limit for DMA -- which varies
from arch to arch, possibly even from motherboard to motherboard within an
arch. Possibly a combo of the two would be a Good Thing, though I don't
really see why you would want to specify that the region returned needed
to be <nMB except for the DMA limit.
