Don't worry, you are not alone...

Qt3 and GTK still seem to do a better job at font rendering than Qt4. That's actually the 
main reason why I'm still on KDE 3 and I don't feel like upgrading. I found the new 
Konsole unreadable compared to the old one because of the fonts.

I've been trying to fix this for a while now, and one of the step I've always been doing 
in the past (even in KDE3) was to rebuild fontconfig from the latest sources with the 
patented well known feature. It really helps, but still, Qt4 doesn't perform well.

Something I noticed recently, is if you compile Qt4 on both Fedora and Debian, Fedora's 
build will be better than Debian. It seems to respect more your personnal settings. Qt 
4.5 helped a lot on Debian, but still, it's not even at the quality I've been getting on 
Fedora using 4.4, and that's not the quality I've been getting from KDE3/GTK neither.

I'll certainly have a look again, but if you find something useful in the meantime, let me 
know! :)
