Yeah I use that mode on my U64 with GEOS and Megapatch 3. With the 16MB emulated RAM expansion you can create the maximum 9 slots for applications to DMA between so app switching takes one screen refresh and is effectively instant for the user, fully buffer disks to RAM, boot GEOS from RAM, and still have memory unused.
