Vista Needs DirectX 9
Although most games work ok with DirectX 10, which comes built into Windows Vista, some games such as Medieval 2: Total War and Company of Heroes may not work correctly and you're likely to see errors about missing DLLs. If you have these problems (and even if you don't you should still consider it) you should install DirectX 9 on Vista by downloading it from here. This seems to be a problem with the backwards compatibility in DirectX 10 but installing DirectX 9 should solve any problems without causing any new conflicts.

and dx9 and dx10 are installable side by side with zero problems
Does it force applications to use DX10 and if that doesn't work fall back to DX9?
Dual boot = solution.
read up, dx10 is TOTALY INCOMPATABLE WITH ANY OLDER VERSION OF DX dx9L is there to run older games, you need to update it tho because ms didnt get the latest version on the disk(morons)
