Someone was mentioning this in IRC the other day. I'm VERY tempted to try it out on my iMac G4!
MacRumors has an IRC channel?
Just checked it now and Yeah its exactly the same as your picture. if it means any thing I remember the flashed 128MB R9200 AGP card in my G4s would have no acceleration under OS 9 I would get an X on the acceleration extension during booting signifying its not loading I would also get a phantom 640x480 second display on it (sawtooth or MDD it didn't change it)
