Is there any place that lists packages that are 64-bit incompatible? Or, will I just have to march through all my packages and check them one-by-one on CRAN?

An approximation to that is to call 
available.packages(type="win.binary") on both versions, and compare the 
lists.  Packages may fail to appear for reasons other than 
incompatibility, but incompatible packages won't be available in binary
