So when I tested this I plugged my laptop into the ethernet first and
verified the captive portal and outbound path to the internet. I've
been in a lot of hotels that have both WiFi and ethernet where the
ethernet is dead. The results I got were:

 laptop:
 ethernet -- link, initial DHCP address, agreed to captive
 portal, connected to internet;

 soekris:
 vr0 -- No link; no dhcp, no captive portal, no internet;
 vr2 -- link, initial DHCP address, agreed to captive
 portal, connected to internet;

At this point I assumed a dead vr0 port and since the Net5501-xx has
four and I only needed two, I moved on. What puzzles me is that I
expected the vr0 port to remain dead when I returned home. And that's
not what happened.

I completely believe that the hotel's wiring could be the root
issue. If that's the case there's not much that I can do. Does anyone
know if there's something in the Soekris that would exhibit these
symptoms? Could this be a weak power supply?

I won't be travelling again until late June. If the issue comes up
again I'd like to have a strategy to figure out whats going on. If
weak wiring in the hotel is the issue could it be weak enough that it
affects all four ethernet ports on my Net5501?

Thanks for the helpful ideas here Wim!

I replied on the other answer also. I don't remember trying to force a
slower negotiation before I changed ports.

Next time i'm in that situation I'll throw that solution on my list.

What version of OpenBSD are you running?   Since upgrading my
Net5501-60 to OpenBSD 5.8 I've experienced the same issue you see --
no link on the vr network interfaces.

I suspect it is a driver issue in OpenBSD, I see some old threads
about the 'vr' driver but nothing recent.   Same hardware was working
fine plugged into the same switch when running a really old release of
OpenBSD.
