I've installed the most recent version of ESS from subversion. ESS now  
finds both the 32-bit and 64-bit installed versions of R-patched on my  
64-bit Windows 7 system.

One interesting issue. If I open an empty file test.R and navigate via the  
ESS menu, Ie. "Start Process:Other and select the 64 bit version, then the  
following text appears in the buffer:

"ESS [S(R): C:/Program Files/R/R-2.12.1patched/bin/i386/Rterm.exe] starting  
data directory?"

Although this appears to point to the 32-bit version, the 64-bit version  
opens in the R buffer when I hit enter.
