But I've been thinking about this for a while now. My biggest complaint right now about my A4000D is the AGA chipset. It seems to just fly when in 64 or less color mode, but in 256 color mode, work bench crawls, has weird redraws, etc.

A Natami style graphics card is highly unlikely, best available option for the 4000 is a Mediator busboard with Voodoo 3 / Radeon 9250 card.
