The problem is not 64 bitness, but a broken ld program that came with XCode 3.1.  There is a patch to fix this on Wine's Bugzilla and you have to download the source for ld from opensource.apple.com.  Also, there is very little truth to the fact that running X86 processors in 64 bit mode disables v86 mode.  Maybe Apple disabled this in Snow Leopard, but Vista 64 supports running Win16 programs.
