error resuming standby asus sk 06903 xma

Hello. I have recently installed Windows Vista Beta 2 and I have a problem when resuming from standby. Everytime it resumes, I get a blue screen error and after rebooting I get a message telling me there is a solution to my problem. This is what Vista tells me:
"The version of ASUS SK-06903-XMA that you are using, created by Microsoft Update Website, is not completely compatible with this version of Windows. Your computer is missing updates that can fix or prevent the problem you reported. Click the following link to install recommended updates from the Microsoft Update website now:
Microsoft Update Website
Note: If you have not installed the latest Microsoft Update software, you will be asked to upgrade and restart your computer before you can use the website. After restarting, go to the Microsoft Update website. Click Custom Install, select optional software updates from the left, and then install the ASUS SK-06903-XMA updates."
I follow the instructions but I can't see any ASUS SK-06903-XMA update, nor I see the "Custom Install" or "Optional software updates". Windows Update just tells me all updates are installed.
Any suggestion regarding this? Also, a search of ASUS SK-06903-XMA over the internet returns no results....
Thank you in advance!
