The MS information on their 64bit edtition shows upto 8gb only supported on the Basic and 16gb on the Home Premium 64bit editions. The MS information goes as follows.
Memory specifications
All editions of Windows Vista 64-bit provide increased memory support beyond the standard 4 gigabytes (GB) available with 32-bit editions. Refer to the specific edition of Windows Vista 64-bit to determine maximum memory capacity.

While all that is wonderful the praticality of even 4gb at this time lacks. The increased support seen with the Ultimate 64 edition is due to having networking features in that edition not seen in the Home Premium or Basic edtiions. For desktop use the chipsets still haven't cut through the 4gb barrier for those quite yet.
