Erm, not really.

To rename a kernel, you edit Makefile at the root directory
of your linux kernel.

-EXTRAVERSION = -xfs
+EXTRAVERSION = -something-else

How did you build your usb-storage.o drivers? Make sure you
specify the include files when compiling 
(i.e. -I/usr/src/linux-`uname -r`/include). Make sure you
specify -DMODULE too.

Just compile, and load it. If you have problems with 
versionings, turn off modversions in your kernel. That
should work.
