The requirements for Quartz Extreme are pretty specific, and, as noted, the Trident XP2 was never an Apple-supported card in any OEM incarnation. The documentation for this particular card says it supports OpenGL, which is a start, but on top of that there are specific requirements pertaining to texture handling that the hardware has to support. (It's those texture limitations that keep the Rage cards in everything pre-second-rev PB G4's from working.) If the hardware *is* capable enough it might work if the driver itself sets whatever flags it needs to to indicate it's compatible, but... something tells me it's a long shot
(The Trident chip itself seems to be very obscure, hardly used outside of a few very-low-performance embedded applications, and it dates back to at least 2001-ish. The ATI RAGE Mobility was still a current product back then so color me surprised if the 3D accelerator in something made by Trident is more capable than it. Trident has been infamous for producing some of the slowest/worst video cards on the market going back to at least the start of the Clinton administration.)
