IIRC, a discontig memory implementation is needed for the I2 to use
more than 256 MB, due to the memory layout on this machine (with
aliased memory etc -- see the R3000 MC spec).

I kind of lost track of this issue recently, so I may have forgotten
some details and got part of the above totally wrong :)
