No joy on my 15" G4 Powerbook. I got the initial ncurses screen showing the Test CD / Skip choice, and then when Anaconda starts, I get a blank screen. Even the other consoles go blank (Ctrl-Alt-F2 to F4).
I did happen to catch something about no video card detected during Anaconda's startup.
My powerbook has a 1280x854 resolution screen and a Radeon Mobility 9700 (9600).
Maybe I should have pointed to my orignal bugzilla post for additional info:
