Disappointing font rendering with ATI graphics card


I'm using an AMD Athlon64 machine running Suse 10.0 with an AGP graphics card, ATI Radeon 9250 chipset (but YaST identifies it as ATI RV280 5960). Font rendering (in both Gnome and KDE) is unpleasant - it seems 'gritty'. The video display is fine apart from this, but the fonts are not nearly as good as they appear on an Intel machine with onboard Intel 845G graphics - using the same LCD monitor. It's the same story on both machines with Ubuntu and Fedora 4. Also, the four choices in Gnome Control Centre/Fonts make absolutely no visible difference (in the AMD Suse 10 setup).

It's a bit of a bummer because I'm a writer and word-processing is my most important application, and I assembled the AMD machine especially for Linux.

Are there any tweaks I can employ - the Graphics card option settings in YaST make no sense to me. If not, does anyone have any comments about ATI cards and font rendering. I've read that ATI are not as good as Nvidia at keeping their Linux drivers up to date, but would that affect font rendering? 3D acceleration is not important to me. I didn't really want to buy another card but will if I can be sure the fonts will be better.

This is the output from /sbin/lspci:

Many thanks in advance. Oh, and by the way, I did use the search facility, but the only relevant (and informative) post I could find was specifically to do with Slackware.
