Why yes, it would seem that the routers in question are running 
proxy-arp, that puts my mind more at ease knowing WHY the clocks 
connected via the cisco's work.

Yes, it does, supposedly, and it is directly on both subnets, however, i 
just turned it on and things don't seem to be working yet.  I think i 
might upgrade the firmware in the switch when i get a chance, and see if 
that fixes it.  (had to update the firmware on it about a year ago to 
get the routing to work in the first place.)
