I was just looking at the specs for the bp6 and I am not sure if it supports flip chips?
as for the revision, if you buy it new you should be getting the newest revision, you should check the caps around the sockets and see if they are tall or short.
I will try to find a newer board with dual flipchip support, an i815 chipset board might be the way to go.
Here is a link to
