Umm... they probably used the 'Emotion engine' which is implemented (partially) as a MIPS co-processor and partially as a render pipeline. Basically it's a powerful vector engine (also see VIS w/ the UltraSPARC chips). This is different the more recent approach of using GPU's that are generally programmable for computation.

Not that I know of and it wouldn't really be a second processor.

For web/mysql/e-mail you are probably going to need high throughput and good disk access / I/O rather than floating point performance. Even if you could use a graphics card like this (and TBH I doubt the Ultra 3D can be used in this way) then you wouldn't really help as the work load isn't FP intensive. > Any thoughts, tips, hints or urls would be appreciated. If you are interested in using the Ultra 3D for something odd then look at the kernel drivers and docs from Sun to look at what it's exact capabilities are. If you are interested in looking at processing using GPUs, start by hunting some of the recent academic papers on it; which I believe have mostly been using x86 / AGP cards.
