'Fraid not.  While the A2630 RAM isn't on the expansion bus, it is in fact
autoconfiguring memory, in the same logical address space as expansion bus
memory.  This is necessary to allow expansion bus devices DMA access to the
A2630's memory.  Motherboard memory isn't autoconfiguring memory, so that's
not an issue.  In the above case, the GVP memory probably gets shut up, though
it would get added if you dropped it down to 4 megs.
