Ok, so my last post was wrong. The setting in drirc does NOT sync to vblank. My latest guess is that it's not supported in the r300 branch of the radeon driver, but I can't tell for sure.
Here's the major problem again: where do I go to ask? I've checked the xorg docs, the dri wiki (who's search interface SUCKS, btw), the Fedora boards...no one seems to know. Also, forums would be GREAT for something like this, but it seems like as you trickle down deeper, you get more unsearchable listservs that require hours of browsing to look for an appropriate discussion.
That doesn't even TOUCH on the terminology issue. What's it called? Vertical blank signal? Vblank? Vertical refresh signal? Google isn't helping.
I'm frustrated.
