I had to do a f6, esc, (selecting nomodeset doesn't appear to change the line) then manually added the following in the boot line:
i915.modeset=0 radeon.modeset=0
I then get the purple ubuntu screen with the 5 red dots and then thats all. Pressing the power button, wait for the CD to pop out, then press the enter key on the wireless seems to cleanly shutdown.
Bug still appears in Beta2, on my iMac11,1 i7 -
