Under 24 bit addressing there is 1M of address space assigned to each Slot. Does that mean that a video card would be limited to 1 MB of VRAM when using 24 bit addressing? Or is there some trick one can do such as telling the Mac to treat each address as a pixel (32 bits per address). One would still be limited to 1M pixels, but more color depth would be available. Or is there some other workaround available?

It seems like this would be a strong limit on monitor sizes connected to the SE/30 although, I guess Mode32 could just be a requirement for use with a larger capacity video card. Does Mode32 affect Slot address assignment or just DRAM capacity?
