OK. Quit pain solved: An iSight plugged into the front FW port. Removing it solved the quitting. Still wondering about that 4-4 thing, though? In system profiler the sub units look as follows:
Io Unit:
Unit Software Version: 0x20
Unit Spec ID: 0xA27
Io Unit:
Unit Software Version: 0x22
Unit Spec ID: 0xA27
Io Unit:
Unit Software Version: 0x11
Unit Spec ID: 0xA27
Io Unit:
Unit Software Version: 0x24
Unit Spec ID: 0xA27
Guess that implies the 22-27 version is in fact installed?
