I agree it would be nice to have the fast ram and the 32 bits ram.
Thomas seems to know what to do about this.

I've still got a lot of work on the 68030 cycles (many access times are still not correctly taken into account), and I'd like to improve the crossbar DMA and start the Videl emulation.
That's probably enough for me for now
