Can rc.conf work that way?  rc.conf is just a shell script, and you're 
assigning values to variables, so the second declaration would overwrite 
the first.  As to why that would have worked for you...  After dhclient 
runs successfully once, some of the information is kept on disk 
(resolv.conf, default route).  Maybe it was enough?

There's an example of specifying media type in the dhclient.conf man
