This is a misleading message that should be fixed.  It only means that 
Rmgr is not running on L4/486, and that it *will* try to request 4-MB
pages from its Sigma0 memory server.

Can you give us a hint on what exectly went wrong, or where the system 
hung?

They should run on both architectures.  However, I haven't tested
Fiasco (main) a lot on 486s, so there may be minor problems.  The
other programs have been tested on both Pentiums and 486s.
