Note the docs use the word "currently", which means it might be
possible later.  I suspect it was a case of "we can't directly access
the GPU, so it's a hard job, lets just do a frame buffer now and do
fancy GPU stuff later".  In other words, do the simple thing now, so
that there is something that is usable, get it out the door, then work
on doing all that complex, juicy stuff.  Just a guess.  B-)

All access to the GPU is through the hypervisor, that adds an extra
layer.  So your standard nVdia binary video driver is unlikely to work,
even if it does support that particular GPU.

Also note, YDL 5 will feature the E17 window manager.  E17 gives you
lots of eye candy, speed, and low resource usage.  It does all this
without using any graphics hardware acceleration.

Lets face facts, the 3D games available for Linux pale in comparison to
the actual PS3 games that will be available.  You don't buy a PS3 to
play linux games on it.  You install linux on a PS3 for other reasons.
Well, that's why I'm getting one.  B-)

(Yes, I'm ignoring non game 3D apps.  I don't use any.  Hell, I barely
have time to play games.)
