I have the docs for the T2R and T2R4, though the NDA politely asks that I not distribute them and I'm inclined to obey it. It does have stipple color expansion. The 3D engine also has a pile of palettized texture formats, listed of the form "1 bpt 0565", which I take to mean "one bit of index into a palette of r5g6b5 colors". There is also a display list processor on the chip (not implemented in the X driver), which appears to have a mode for hardware acceleration of aliased glyphs, which for a console driver might be all you need. - ajax
