I don't use NM yet, but I also use local DNS as well to get around this 
problem and also to add another very nice feature: Union two domains 
together.  You can't do this with resolver.  Each nameserver 
in /etc/resolv.conf needs to be a complete set that are identical to 
other.  It will not say, "hey I can't find foo in nameserver 1, so let 
me go find it in nameserver 2."

However, local DNS, can say, "hey foo is in bar.com, so i'm going to 
look up these set of forwarders that work for bar.com; for everything 
else, I'll look up these other set of forwarders".

Unioning of domains really bit me in the butt for my laptop use when 
connecting to the internet and to our corporate VPN.  By using local 
DNS, I also sculpt the packets better by not always trying to resolve 
against the VPN-provided DNS servers.

If this type of setup was added to NM, it would be very, very nice.

Anyway, just my experience with the issue. YMMV.
