Sounds like you have udev rules that put devices in the right places, 
but that fail with the other cards--check those rules and update them 
for the swapped cards.  I don't know of any way swapping a PVR-250 for a 
PVR-250 could cause problems--so that means something else is causing a 
problem.  If you're saying the only problem you see after swapping them 
is mythbackend crashing, that means you're changing something 
mythbackend relies on, and mythbackend logs would tell you what that is.
