Well, not quite no problem, but it works.  Can't recall all the gory
details now, but it was a bit tricky getting rid of 32-bit Firefox and
Mozilla without breaking other things.  IIRC, had to do some ugly stuff
with rpm --force to get rid of 64-bit browsers, leave required 64-bit
libs, and install 32-bit browsers to run 32-bit plugins such as
Acroread.

Running VMwareWorkstation 5.0 on a dual Opteron Tyan K8W MB.  Works
well.

Agree.  Use the 32-bit stuff where required, 64-bit whenever possible.
