Ah, VIA's a bit different.  ;o)  They've been very OSS friendly 
in the last year or so.  I've got a few PDFs of theirs also, 
possibly the same ones you have.

Alan has been doing a fair bit of work on the EPIA boards lately, 
and has 3D accel working now (with XFree86).  It'd be nice to 
assimilate him into fd.o xserver hacking.  ;o)
