	HDToolBox totally ignores 2090's: it doesn't know them from a hole in
the head.

	The trick to using a 2090: nofastmem BEFORE binddrivers, and use a
mask in your mountlist restricting dma to 24-bit space, and a bufmemtype that 
forces buffers into chip mem.  You can turn fast mem on again after
binddrivers.  If it's a 2090A (autoboot roms), you'll have to pull the ROMS.
