Not sure if this is related, but I get the same thing on my G4 GbE/ADC
when starting X - blank screen, then C-M-BS doesn't return syscons, nor
does anything else. strangely enough if I type 'shutdown -h now' on a
known root console, the system shuts down. I do experience a display
hanng though.

I only know this to be an issue with X - I haven't played with anything
else yet. 

(7.1-BETA, -CURRENT unknown.) 

ATi Rage 128 Pro. 

Also, Justin, I envy you your machine. It sounds frickin' sweeeeeet. :)
