You only other options are:

1) rebuild Python itself and every other extension you use.

2) use MingGW, after googling to see the hacks you need to make it work. 
It's not very hard.

3) figure out how the heck to build extensions with a different MS 
compiler than the one used to build Python. You'd think that if you can 
build extensions with a completely different compiler (mingw) then you 
could build them with a different version of the MS compiler. AFAIK, the 
issue is not the compiler, but the system libs -- different versions of 
VS also use different versions of the basic C libs. If you could figure 
out how to get a newer compiler to use older libs, you may be able to 
get it to work. However, I don't think anyone has ever done this, and 
there area a lot of smart people building Python....

So, yes, going back to VC 7 is probably your best bet.
