Why can't you list the second DNS server in /etc/resolv.conf?  Also you 
can specify multiple domains to search for base names in.  EG:

/etc/resolv.conf:
search hq.pogolinux.com ks.pogolinux.com
nameserver 192.168.1.2
nameserver 192.168.2.2

On this system, one nic is .1 subnet, while the other nic is .2 subnet.  
One subnet is hq, the other is ks.  Given that I listed both search 
domains, I can do things like "ping fred" and "ping barney"  given that 
fred is on HQ and barney is on KS.  Name lookups will work and things 
will be happy.
