I get the same results looking at that zone from here either on NT4
machines or on our Linux DNS machines.  On other zones, including ours,
I don't see the uppercase in the PTR records from either NT or Unix.

Are you sure you don't have uppercase on the names in the REVERSE files?
    (e.g. for 149.54.244.128.in-addr.arpa)
