So, you want some Targets to poll every 5min and some to poll every 1min?
Simple, just have 2 instances of MRTG, one handling the 5min interval and
one for the 1min interval.

Note that if you're using RRDtool 1.3.4 or later with MRTG in daemon mode
under Linux/UNIX it uses some nice hinting code and memory mapped IO to
greatly improve IO performance, particularly if you don't have so many
