When will the XPS M1730 fully support Windows 7?

I've browsed various forums and not seen a confirmed answer from our friends at Dell.  The M1730 is MORE than capable of running Windows 7 - I currently have Windows 7 Ultimate 64-bit RTM installed.  Everything seems to work well for the most part, although I do experience video driver crashes from time-to-time.  They tend to occur when I'm playing World of Warcraft (not the most graphically intense application out there).  Searching the internets yielded no solid results, but I suspect it may be a heat issue.  That leads me to believe that this is the reason the M1730 is NOT currently on the Windows 7 supported hardware list, but I'd like to know specifically why and if/when we will see Windows 7 drivers and support from Dell.

Video drivers are the latest and greatest from Nvidia at the time of this posting and all other drivers are either Windows 7 native or Windows 7 drivers from the manufacturer.

Windows Advisor states that the M1730 fully supports Windows 7, why doesn't Dell?
