people have started to use 64bit builds of mozilla on windows. our general instructions to people who have crashes is to use windbg which uses the symbol server. without symbols on the symbol server, the result is bad. the users get upset and i get upset and everyone gets upset. getting breakpad working is unrelated, as pushed symbols can be used by windbg.
Enabling Breakpad in configure should be as simple as fixing the case statement here to include x86-64: http://mxr.mozilla.org/mozilla-central/source/configure.in#6119 Breakpad basically worked on 64-bit Windows last I checked (since all the dumping is done via DbgHelp.dll anyway), we just don't dump the frame data (bug 548035), so we won't get anything but the tops of stacks on the server-side. But it should make "buildsymbols/uploadsymbols" work, anyway, which would get you symbol server support.
(make me searchable in bugzilla) could have used x64 symbols this weekend
The Win64 build machines don't have VC 2005 installed, so we'll need to fix bug 575519 first.

Note that we probably need bug 575519 to land as well. Drivers: this patch should have zero impact on anything but Win64 builds.
