I think there's a bit more going on.  I'm pretty sure that fvdl
had earlier versions of bge working on sparc64.  I have had problems
(perhaps the same) with a similar (perhaps the same) card on XScale.
I started looking into them, but didn't get very far.  At the time,
I was thinking that it was a memory/cache coherency problem, but
I didn't get as far as confirming that.

In my case, it was really looking like the card just wasn't responsive
to much at all.
