Sure.  All the Debian packages are at:

   http://www.toolchain.org/~ahs3/llvm

The 'llvm-cfe' package contains the CFE I build from scratch.  If
you pull down the source for the packages from that location, there's
a script called build.sh that starts from source tarballs and builds 
the binaries for the front-end and LLVM (I should probably submit that
script to the utils directory for LLVM...).  The LLVM 1.4 packages 
are the most stable of the ones on the site; the 1.5 packages are in
progress.

BTW, I also run a nightly tester for x86_64.  I'm not real happy with
the results right now, and haven't had much time to spend on it, but 
they're at http://www.toolchain.org/~ahs3/Sites/amd64/ if you're
interested.
