Let me explain how it works:
We don't make any difference between server or client platforms when
building our drivers. Initially, all the files, mentioned above (inf,
cat, sys, and pdb), are absolutely the same. Then the files go to QE for
WHQL testing. QE tests the same drivers on both, desktop and server
platforms, and creates two different submissions files for sending them
to WHQL dashboard togather with the original "cat" file.
As the result, we have two different cat files created from the same
original one.

As far as I remember, there shouldn't be any problem to swap these two
cat files, and use them interchangeable. But it will be better get some
conformation from QE team.
