Tim, I have had a similar problem with two different Power Mac G5s, but it occurred when I migrated them from MacOS 10.4 to MacOS 10.5. Also, the machines got to the blue screen just before login, and then stayed there forever with no further audible hard-disk activity.
1 After much research and trying different solutions, a run of Apple Hardware Test on the first Mac showed that the problem was a faulty DIMM. Replaced that DIMM and problem solved. 2 After resetting the power management unit, and the PRAM, on the second Mac the problem was solved. I hope that in your case it is neither of the above because I have no idea about whether a Mac Mini even has a power management unit reset switch, and getting at a Mini's memory is difficult.
