You don't have enough video RAM. 1Gb is minimum for Dalaran.
What is your source for this information? I'd love to test your theory out but I haven't figured out a way to track video memory usage in Vista.
WoW was using around 200M video RAM a while ago before 3.0 patch which brought us some new fancy stuff definitely consuming even more RAM. I measured it on my old rig at 1280x1024 in Shattrah using RivaTuner under WinXP. Now with higher resolution and higher video settings my guess is that in Dalaran your main client alone is using at least around 300-400M, I dont have XP installed anymore to test it Add 4x slave clients that are using video RAM too and you end up much higher than your 512M.
One more notice: after I installed WDDM1.1 drivers which offer better video memory management, almost all my lags in Dalaran on 1024Mb 4870 are gone. So my guess is that 5-boxed WoW is using slightly more than 1Gb video memory and these drivers could save some memory enough to fit into videocard's installed RAM.
