I plan to extend it out to 8 in 3.5 development.  The t&l module supports 12,
the software rasterizer pretty much supports an infinite number, the core
state management code currently is limited to 4 but can easily extend that out
to 8 by rearranging some flags.

Don't know, sorry.

I wouldn't be suprised to see other implementations ramping up for more units
in the near future.
