On my last backpacking trip I decided that wearing my gun on the hip-belt of my pack was less than ideal. Have any of you guys seen or used a drop-leg holster with a revolver?

I don't know of any, but there are some other alternatives out there.
Ruger, Alaskan Sportsman Holsters and I'm sure others as well have a shoulder type rig that allows carry without getting in the way of a back pack.

I know a lot of people who like the Chesty Puller (http://www.simplyrugged.com/leather_goods/chesty_puller_conv.html) holster from Simply Rugged for that job.
