I tested the PGX32 yesterday.  Indeed, it works flawlessly in the Ultra45, as I'd hoped.  The machine picks it right up and the Solaris 10 PGX32 driver works fine.  The card also picked up the DDC from the 19" Sun LCD it is hooked to, and set the video timings to match.  The PGX32 has a preset mode (1280x1024 at 60) that's perfect for this LCD.
The PGX32 is quite sluggish, but it's fine for what I need it for.
