Erm... I just realised that I forgot to backup known "good" kexts. Seems that I'm not going back in this MacOS instance....

PS: gee, tried of tweaking Adium again and again...

PPS: have I coped correct kexts?.. Shouldn't be here by now

PPPS: gone reinstalling GU1 from scratch. btw OSX no longer detects my USB BT dongle...
