The "Desktop" item has XF3-style static servers for some old Trident chips, 
the "Discontinued" item has some other bits of Trident history.

I'm fairly certain the XP4 began life as a Trident product, though XGI might 
be doing more with it now.  Some of the XGI Volari chips seem to have XPn 
markings as well.

There is a (non-working, non-even-building) trident driver in Mesa CVS that 
Alan claimed to have working on some model of CyberBlade.  Whether it works 
on the XP4 I have no idea.

I would love to know if it's possible to obtain documentation for the Trident 
and XGI cards.  My emails (okay, email) to XGI have thus far gone unanswered.
