 i've been keeping an eye on them for some time (since they came out
with the chip that went into the ben nanonote and the incredible GBP
99 8in laptop back in 2008 what was it... achh it's pretty famous,
sold under over 30 different brands... somethingsomething 400... got
it! http://en.wikipedia.org/wiki/Skytone_Alpha_400 aaawesome machine)

 if i recall correctly the source code tends to make its way onto
their ftp server as a matter of course, including the 2d video
acceleration.  video decoding and any acceleration is done through
X-Burst is done *shudder* as some awk scripts that parse standard
software libre c source code, converting sections to assembler by hand
(!!!)  hey if it works... :)
