I’m reluctant to reply to this because people can be VERY pickey, very emotional and MASSIVELY subjective about their fonts. I’ve had users complain about FONTs, and then finally get their FONTS working perfectly. When they posted the output which they noted was finally perfect, their FONTS were HORRIBLE in my view. YET when I looked at the FONTS they started with, they were great, and they absolutely RUINED (in my view) some excellent fonts for questionable FONT tuning. Yet they swore up in down it was an improvement.
Concusion: this is subjective.
Still, you could download fetchmsttfonts for openSUSE-11.2, and rebuild the rpm for openSUSE-11.3, and use it on 11.3. You can find fetchmsttfonts in the build service.
The Nouveau driver does not work well on all NVIDIA cards. Fonts are not too good on my laptop using the nouveau driver, though performance is incredible.
You may need the NVIDIA proprietary driver, that should at least give you the very nice font rendering I see every day.
