I was too fast to say RC1 works okay - hotkeys and altgr-keyboard layouts may not work because of last-minute FF changes. I've mostly finished porting UberKern to C (bye bye PB), so... therefore i declare original UberKern / patcher obsolete. As soon as i'll finish APIs, test, convert them and contact Xeno86 you can expect Firefox 3 running on your desk with new KernelEx. RC1 fix will be there. I'll try to explore the possibilities to run other new GTK+ programs. UberKern may revive as a patcher for InkScape or Gnumeric or sth else. Me and Xeno86 are exploring the possibilities of creating new KernelEx architecture. If it goes well, you won't ever have to patch a program again and somehow violate some strange mind's license.
