I disagree with this personally.  If one doesn't build from kernel.org 
srcs, how else does the code that winds up in your favorite distro 
going to get enough checking to catch small, but showstopper bugs in 
as many environments as the distro's kernels will have to run on when 
the distro gets around to issueing an rpm?

I'm not much of a coder anymore, too many years (70) on the grey 
matter.  I think I was the most productive in my 50's at carving out 
C.  Or assembly, whatever. But that doesn't stop me from following an 
interesting thread of kernels such as the RT kernel patches Ingo 
Molnar is working on, and which some parts of have already made it 
into mainline.  So everytime he issues a new patch, I build it and 
run it just because if something goes all agaga on my hardware, the 
exact patch that did it, or was wrong, can be identified and fixed 
long before you folks ever get to play with it in rpm format.

[root at coyote /]# uname -r
2.6.11-rc3-V0.7.38-01-RT

Thats my contribution to the progress of linux in general.  I'm one of  
the canarys in the coal mines.  Somebody needs to do it now don't 
they?

Like you said above, "But its not an RPM."  <shrug>

For the same reason, I haven't run the make install in years, 
prefering to do my own grub.conf/menu.lst editing, its much safer as 
the previous working entry is not removed until *I* remove it, 
probably a long way down the log when I'm forced to play space patrol 
in my 100 meg /boot partition.  My own 'makeit' script takes care of 
all the required copying.  Grub is the best thing to come down the 
pike since bottled beer, and most folks don't use 50% of its 
capabilities.
