I'm the one that proposed the S3 Trio/Virge idea.
The greatest thing about this card is that almost every operating  
system has or had a driver for it, and has also been used in non-x86  
machines extensively.

If you need testing or getting information from a real working card (I  
have a couple of them, all for x86 unfortuneately) just mail me.
