Xerox 6250 drivers issues with OSX 10.6

Xerox state their driver for the Xerox Phaser 6250 is fully compatible with 10.6 but its not. Tested on two mac's running 10.6 both have the same issue. The print dialog does not display any paper sizes, this happens in almost all applications. A mac running 10.5 does not exhibit the same problem and displays all the paper sizes. All mac's tested are intel machines.

I have tried running the Xerox Phaser 6250 printer on a Xerox Phaser 6300 driver which does display all the paper sizes in the print dialog. Although it prints perfectly some of the time on this driver, as it was not coded for that model sometimes does not print via some applications.

I have called Xerox CS and they were no help at all. Is anyone else running a Xerox 6250 on OSX 10.6 successfully?
