Yes, totally playable framerates - well over 30fps at 800x600. I'm running it on a 500MHz G4 Sawtooth system, so with 66MHz PCI and 2x AGP it's not like I have massive bus width. My display card is a Radeon.
There are occasional pauses that I'm trying to eliminate, but during testing my system was running Apache and a bunch of support services. I'd like to find a hack that would let me give higher priority to a running process so I could essentially shut down the Window Manager (which does a huge amount of memory-juggling) while a game is running.
I tried running with the built-in OpenGL support and found no significant difference, but I need to go back and do a little more messing around to find an optimal arrangement.
I'm guessing that 10.1 will speed things up even more, but we'll see!
