Can I use All Seeing Eye (ASE) to find and play in OFP: Resistance MP servers?

Yes. As of ASE version 1.9.3, released at the end of September 2002, native support for OFP: Resistance was added to ASE. You can download ASE from here.

For users with older versions of ASE who want to try to get ASE and OFP: Resistance to work together, have a look at how to try to do this the old fashioned way.
