Kyle Orland from Joystiq cruised through the Sony PAL Backwards Compatibility web site here to crunch some figures. So far, 43.72% don’t work, 35.69% do work, and 20.59% work with issues (from minor to severe).

I expect future revisions of the firmware should bring that number up, but personally I think Sony should have stuck to including the hardware, worked on the emulation for a future version of the PlayStation 3 including the Cell 0.65 nm core shrink rather than trying to scramble to get it done now for the PAL launch.
