8139cp here.  Seems to have picked up this behaviour since SL10.1beta2 or so, 
still in beta4.

carrier is 1 before and after, eth0 is UP before and after, restarting NM 
doesn't help, nor does stopping NM, rmmod, modprobe, and starting NM.  

I didn't think it is NM related, as I could not configure the network by hand 
after resume.   However, I just switched my network config to SUSE 
traditional ifup+ifplugd (joys of flexibility), and although eth0 does not 
work on resume, rcnetwork restart fixes it, whereas when NM is in charge, 
this does not help.  So my understanding is NM is not the direct cause but is 
a contributing factor.
