This only fails if ssh'ing from another (any) domU to the 2.6.9-67.EL xenU/domU

ssh-ing from dom0 works; ssh-ing from another remote machine works also.
I think you mentioned that this ended up being just a bug in the RHEL-4 PV

close this bug out?
Correct, it's only in rhel4-xenU.
thought I closed this bz.... will do so now...
