Wrong.  It's not a functional equivalence, it's a literal equivalence.
 It will *always* be:

Backend->SomeHardware->[IR]->STB

where "SomeHardware" could be a PVR-150, a PVR-250, a Serial to IR
adapter, whatever.  It's literally 100% the same as using any other
device to do IR blasting.  The HD-PVR wiki page emphasizes configuring
IR on the HD-PVr because the wiki page is about the HD-PVR.  Just as a
PVR-150 page would emphasize configuring IR on a PVR-150.
