I had pretty reasonable luck running a codaserver on a Powercenter Pro 180
(604e/180) running Yellowdog Linux 1.2, 2.2.7 kernel.  I had mixed results
with the client on my G4/400 (PCI graphics) running Yellowdog Linux 1.2, 
2.2.14(16?) kernel and most of the problems were related to glibc bug in
the libresolv.a IIRC, although I might have also had some problems
transferring large amounts of data.  I believe I was running Coda 5.3.7.

As for RPMS, I just built the RPMS using the script in the tools directory
of the src distribution...
