PCMCIA doesn't work in docking station

[Curt McKelvey <mckelvey wrc xerox com>]

I am using RedHat 4.2 on an NEC Versa 6200NT notebook.  I have a PCMCIA
Ethernet card, a 3Com 589D, in one of its two slots.  At first, I
couldn't get the PCMCIA to work, so I went out to the PCMCIA site to get
the latest version (2.9.11), compiled and installed it.  On the laptop
it works fine.  Here are the pertinent boot messages:

However, when I boot in the docking station, the PCMCIA fails:

I just changed this laptop to RedHat 4.2 from Debian 1.2, though both
are running kernel 2.0.30.  With the old Debian, I was running PCMCIA
2.9.5.  But it worked fine both in and out of the docking station.  So
now, how do I get it to work with RedHat?  Any ideas on where to start?  

Thanks,
Curt
