Right, and the best solution to this problem is to include in the
signature the name of the module.  (One way of doing this is adding
the module name into the cryptographic checksum which is then
digitally signed by the kernel module key; we would have to bump the
version number of the signature format, obviously.)  This binds the
name of the module into the digital signature so that it can't be
renamed.
