I suspect this is only a radeon PowerPC problem. Userspace Mode Setting has been removed and the current kernel config doesn't allow KMS to function (the radeonfb module is built-in). What is happening is that the fbdev driver is used instead in 8 bit pseudo colour. Why that causes ubiquity to not display anythng I don't know. The window sort of grabs the image of background or other windows/menus that are placed over it, but doesn't display images of its own.

Using the yaboot parameters "video=ofonly radeon.agpmode=-1" (which enables KMS and a functioning radeon driver) ubiquity works fine.
