To be practical, both cost and power wise, this solution would have
to be based on an embedded chip.
AMD Geode processors can be used to make a graphics card. They
support MMX and 3D-NOW. AMD states that they fully support Linux
on these.

The GX or LX would be a single chip solution. It would be
inexpensive, but I don't know how fast it would be. They have the
advantage of having hardware VGA. The LX is a bit faster than the GX.
You do *not* want to use the Geode, LX or GX, for video processing
except in a very specialized app.
There is actually a discussion on [EMAIL PROTECTED] right now talking
about using OpenGL (read Mesa)
on the LX they use for the XO. It has nowhere near the needed
processing power to run that - I assume
any other OpenGL implementations would be as limited, and would not
compete with even 7200-era
cards. A possibility could be the Xscale and intel 2700:
http://en.wikipedia.org/wiki/Intel_2700G
which supports OpenGL ES.
Also, this information might be useful to us:
The 2700G performs Inverse Zig-Zag, Inverse Discrete Cosine
Transform, and Motion Compensation to speed up MPEG-1, MPEG-2, MPEG-4
and WMV video decoding. The accelerator can decode MPEG-1, 2 and WMV
at 720x480 (DVD Resolution) and MPEG-4 at 640x480, both at over 30
frames per second.
These all run at 75 Mhz - It is likely that we will be able to decode
slightly better than this if we implement
those features. Given the R&D intel must have put into this chip,
that is probably where 99% of the CPU
power goes.
