T30 w/ Port Replicator problem

I am running a SuSE Linux 9.0 PRO install on my Thinkpad T30.  All works great 
and have had only one problem.  When docked I can not make use of my 4 USB 
ports on the back side of the docking station (port replicator).  I do; 
however, have access to my PS/2 Keyboard and mouse jacks, Serial, Parallel, 
and Video ports.

Has anyone been able to configure their distro in such a way that would allow 
access to the USB devices?  I have tested this with Red Hat EL 3.0 and have 
seen the same problem so I know it is not SuSE only.

Thnaks!
