Ubuntu 9.04 + 4870x2 + Latest ATI Drivers = BAD SCREEN

This is 32 bit version of Ubuntu 9.04 with Latest ATI Drivers installed (v9.4) full boot on ASUS P6T Deluxe using ASUS 4870x2 TRI FAN card. Looks like there is some problems with drivers. This card worked fine on earlyer version of Ubuntu with all nice Visuals that Ubuntu offer. FIX IT ! I had to do recovery mode and uninstall drivers so I can get back to desktop. Does anyone know what to do ? Any work around ? Thanks !!!!
