Unfortunately, there are all too many government contractors, who because there are still maps out there in NAD 27 use that as the datum and then give UTM coordinates.
It can be done with many GPS units...

Michael, It's been quite a while but I recall data in NAD27 having units of feet. Regardless, ... Since the data have both lat/lon and some version of UTM, I think the best approach is to use the lat/lon columns to import the data, then v.proj to the common Albers Equal Area location.
