Only random generic troubleshooting items:
- how's your heating? screen corruption looks like memory or bus errors.
are you running powerd?
- can you set up a serial or firewire connection to it and monitor the
machine from there ("screen corruption" may also mean a kernel message
being printed in text mode, in the part of memory now mapped for
graphics - if this is the case you'll see the message over the serial
console).
