That you've been staring at the problem from waaay too close :^)   
Seriously, all you need to do is to define (in Nagios, not  
necessarily in the DNS, although that probably wouldn't hurt)  
separate hosts for the different interfaces, a la

define host{
	use			corp-host
	host_name	mink-ge0
	alias		mink
	address		10.10.10.10
}

define host{
	use			corp-host
	host_name	mink-ge1
	alias		mink
	address		10.10.10.10
}

Once you have that, you just define the services for each "host" as  
appropriate.
