|Yeah, hi, that was me. I posted that (and also this) as anonymous because I do not get access to my DP account (nick ‘QT’) anymore. Lost the password and somehow don’t get along with the confirmation codes I get emailed (on request) from DP.
To your problem: I also bought a Radeon 7500 back in October last year and was fighting with the same problem. Then I found that ChipId option and thought I could try to declare my 7500 Radeon as a regular Radeon VE. And oooops it was working immeditaetely 🙂
Nevertheless I hope that 4.2.0 gives it another boost i.e. for 3D. Currently glxinfo seems to only have AGP 1x although the BIOS is set to 4x. Thus glxgears (and so on) is doing quite bad on my machine at the moment.
I also have a friend who packaged CVS XFree 4.1.99 for Unstable, but I did not want to test that. Rather sticking to 18.104.22.168 (using ChipId option) and waiting for the official release.
I am happy to read that this option also helped you now…
Have fun! :^)
