And finally, mozilla-xulrunner with freetype2 and system-cairo enabled is in my home repository.
Here is it:
Index of /repositories/home:/Fisiu/openSUSE_11.0
To get subpixel hinting in Firefox and other Gtk applications You also need install cairo package from openSUSE 10.3 Update repo:
Index of /update/10.3/rpm
Choose Your arch (i586 or x86_64) and download cairo and/or cairo-devel packeges and install them.
