Exactly how would you want to do a binary upgrade on a custom-configured 
kernel? (I.E.: A custom binary.) And can you name any OS that can do that?

Although you don't have to replace the kernel with the generic, if you are 
doing a source upgrade.  You should be able to do a standard source 
upgrade.  (Making sure, of course, that your custom kernel's configuration 
is still valid for the newer source.)  I might *recommend* replacing with a 
generic during the upgrade, just because it's safer to be upgrading to the 
tested kernel, but it shouldn't be required.
