Una bella sfida: KERNEL PANIC

[Lyd]

Ho trascritto a mano l'errore che si presenta, nella speranza che qualcuno di voi riesca a dirmi da dove proviene. Io le ho provate tutte, ho tolto anche gli slot di ram, ma il problema si ripresenta.
E' un Imac G5 all in one. 1.5Gb ram e 1.8GHZ cpu.
Tanta stima per chi mi risolve il problema

sicuro che sia tutto il contenuto del file? cmq in genere kernel trap indica un problema hw o cmq legato a dei driver di periferica ..
hai provato a fare il boot in single user mode? (http://support.apple.com/kb/HT1492)

Prima di tutto grazie del consiglio e dell'attenzione!
Questo è tutto il contenuto dell'ultimo errore.
Non ho provato a bootare in single user, qualche tempo fa però avevo reinstallato il s.o.
Un altro vecchio errore, che riporto sotto, fa riferimento a dei driver.
PS: Questo mac viaggia senza periferiche esterne. Solo mouse e tastiera.
