But if I follow the directions in the release notes, I get an 
incorrectly named rpm, to wit:

kernel-2.6.151.2054_FC5-2.x86_64.rpm

It should be 2.6.15-1.whatever, not 2.6.151.whatever

Here's the relevant section from the release notes.

Every kernel gets a name based on its version number. This is the value 
the uname -r command displays. The kernel name is defined by the first 
four lines of the kernel Makefile. The Makefile has been changed to 
generate a kernel with a different name from that of the running kernel. 
To be accepted by the running kernel, a module must be compiled for a 
kernel with the correct name. To do this, you must edit the kernel Makefile.

For example, if the uname -r returns the string 2.6.15-1.1948_FC5 , 
change the EXTRAVERSION definition from this:

EXTRAVERSION = -prep

to this:

EXTRAVERSION = -1.1948_FC5

That is, substitute everything from the final dash onward.
