This essentially boils down to a copyright notice.  So I think it is

This is an additional restriction on top of what is allowed by GPLv2+.
That, unfortunately, makes it incompatible.

This does not allow modification, so it is definitely incompatible
with GPLv2+.  It also restricts how you can use it.  In addition,
Debian will not distribute it in main, since Debian guarantees that
people can do things like sell installer DVD's with the contents of
main.  If you want to distribute this software linked to a GPLv2+
project, you will have to ask for a new license from FBH.
