For most drivers I don't think it will. Most drivers will just say "look I
can do THIS much. I don't give a flying fish about how much of
that you actually use". At least in the probing code.

In code of say a scsi driver that has to pick some dma descriptor format it's a different
matter of course, but there you have to check SOMETHING, either a variable
you stored during probing, or now the effective mask....
