Yes and no. There's some special hardware there, such as a DMA engine
that I think can be used as a screen-to-screen blitter, but in typical
Sun fashion it's undocumented. :-(
> Did Sun ever make an accelerated 24-bit card?
See the SUNW,leo that I mentioned earlier - it occupies two slots, but
it's got 24 bits of colour depth and according to Sun's doc is has
quite a lot of 3D rendering hardware - though, again, it's not
documented as far as I've been able to find.
