That's a nice idea. I remember seeing a similar patch for old amigas, it would be nice to have a CGX5 compatible version that allowed Efika owners to use slow ram instead of running out of memory. But I can't remember the name of the app. AFAIK it was written for picasso96.

I don't know how MOS maps its memory internally, maybe locking a big 64MB "bitmap" in gfx card ram and calling some exec function to add memory to the system would be enough. I don't know if MOS allows that...

I guess that the MOS Team would prefer to keep it as a third party patch but it would be nice to have access to that unused ram. A Radeon9250 will happily work with 32MB and the remaining 96MB could be used for other stuff.
