A couple of things, first there is a Boot Camp forum so if you want support I'd think that would be the best venue.
As you have discovered Boot Camp only supports Windows 7 on the current machines so you are in a box if you must run on Boot Camp. However instead of using Boot Camp you can use virtualization software such as Parallels or VMWare Fusion which perform very well. The are many advantages of virtualization one primary one is you can still run XP. Others include being able to run MS Windows within OS X so you can use both OS's simultaneously. The only downside to virtualization is if you run graphics intensive apps (3D Game, CAD/CAM, 3D rendering) then performance will not be as good as with Boot Camp. However for almost all other apps performance is really good and most cases users don't complain.
While it will cost a few dollars (I believe about $79) virtualization is a very solid alternative.
