Thanks Duncan.  Here's what I come up with.  Anything obviously missing?
 I'd think there'd be more incompatibilities than just these few...

In 32-bit: > pkgs32 = available.packages(type="win.binary")
In 64-bit: > pkgs64 = available.packages(type="win.binary")

> pkgnames32 = pkgs32[,"Package"]
> pkgnames64 = pkgs64[,"Package"]

> as.character(pkgnames32[which(is.na(match(pkgnames32, pkgnames64)))])
[1] "RSVGTipsDevice" "RSvgDevice"     "eco"            "rcqp"
"sparsenet"      "hdf5"
