Hmm, this bug exists on lowly Radeon 7000 cards as well; do they support VBOs?

Does the maximum size of a single command stream increase in subsequent Radeon
iterations? Because on rv100 and rv280, the X server must be restarted, but the
X server recovers with my RV350 and handles the stream fine with my RV790.

(BTW, how does a "stream" have a "maximum size" anyway? By mere definition of a
"stream", I'd expect it to "start" and then chatter away until it met an "end"
marker. So I suspect it doesn't work like that really ... ;-).)
