I have an Intel iMac, Mid-2007 model or MB878LL and I'm unable to load the 64 bit DVD I downloaded from TechNet for Windows 7.

I read here that 64 bit Vista is only supported on select Macs.

Is this true? Is there (until Snow Lepard launch) no support for 64 bit Windows 7 on my machine? Is this a boot camp limitation or just Apple trying to force me to upgrade?

If this isn't possible, I think it's a terrible waste if you ask me.

Or, has anyone been able to get this to work, and be stable?

It's a good bet that if 64 Vista isn't supported than 64 7 won't be either.

64 bit Operating Systems are not supported on the iMac in Boot Camp. Been there, tried that, I get a lovely error. – EvilChookie Aug 19 '09 at 15:34
@EvilChookie: Yea, you get two options and blinking prompt you can't type into. – Chris Aug 19 '09 at 15:38

Windows Vista x64 and here is the addendum for Windows 7 x64
