Yes, of course there are a handful of other applications (mostly ancient
and unsupported codes) which require a 32-bit glibc. But it's really
only Chimera which needs all of the X libraries etc. to get pulled in.

We've already discussed using our MODELLER package in combination with
Chimera. The next public release of MODELLER will primarily be made
available as a Python module, and we are exploring the options for using
this directly with Chimera (rather than having it generate input files
and run a subprocess). This works just fine for 32-bit, but not for
x86_64 unless we build Modeller as a 32-bit application. Given the large
performance boost we've seen for our x86_64 builds vs. i386, we are
rather reluctant to do that.
