Chris, after seeing this message I have tested -rc6 on G33 as well and 
can confirm that it is broken.
I can see only "unpacking" message - very very brief - and then 
absolutely black screen.

I have prepared a custom initrd to ddump the dmesg to a hard disk and 
here are results - "No connectors reported connected with modes".

I attach a run with -rc5 (good) and -rc6 (bad) dmesg dump...

Would it give you enough to work on?

Thanks, Woody
