I had a grey screen hang yesterday whilst getting to know my 17" i7 2.2 MBP
In the end what allowed me to reboot (it wouldn't boot from CD) was disconnecting the machine from everything including power, waiting for just over 10 minutes, and restarting. I have no idea why that would work, and it took me about 3 hours of troubleshooting before I decided to give it a go.
Do a restart once the system comes back up - or you end up having to wait for ten minutes in the case that it freezes up, which seems fairly likely judging by some of the other threads on this board!
