Unreported loss of streaming in atomic read operation

I have a Radeon 7500, using the DRI project's driver.
For those who don't know: There are several* drivers for both ATi and NVidia cards in XFree, the most commonly used display server (a program that takes applications' drawing requests and puts them on the screen, or rather, on the graphics card) in Linux. For NVidia, there's an open-source driver which is pretty much unaccelerated and a proprietary driver which uses the same codebase as NVidia's driver for Windows - and is still considered the best choice for consumers looking for lots and lots of graphics performance on Linux or FreeBSD. For ATi, there are at least two open-source drivers, some from the GATOS project (good for TV-input/output and other 2d goodies), some from the DRI project (some 3d acceleration for models Radeon 8500 and downwards), and one official proprietary driver for models Radeon 8500 and upwards that still does not have a terribly good reputation.
Now, if you got that around your head... I really prefer open-source drivers (they usually cause less trouble than proprietary ones) but it's unfortunately impossible to get a good graphics card from either NVidia or ATi and actually make use of it without proprietary drivers. Fortunately, since I haven't yet been very interested in games that demand more of the graphics card than TuxRacer does (and I haven't played that game for, what, several months - it's just been SMAC and ADOM for me all the time), I can just wait and see what will happen in the patent arena...
* not even considering VESA, SVGA and fbdev and whathaveyou - those work with pretty much every card but... well, they aren't interesting. After all working with them basically consists of setting the display mode and pushing bits into the framebuffer...
