I installed the Radeon LE DDR on my Asus CUV4X this week. Works like a charm, but I highly recommend you reformat your drive to get rid of old drivers/tweaks. As a side note, I used to have a Geforce2 MX on the CUV4X which wouldn't run at AGP 4X no matter what I did. Then I installed the Radeon and AGP 4X is perfectly stable. The Radeon seems to work pretty good with the VIA Apollo 133A chipset.
