In the meantime:
$ sudo adjust the ubuntu docs so it's clear for newbies to which kernel 
version diff against (kernel.org/linux-meta/kernel.ubuntu.com)
and
$ sudo initiate to throw the debian so-called "helper" kernel-tools out of 
ubuntu.

See my other bug filed concerning that.  It took me a few hours to decide how 
to alter the patch for 3.2 (because 1st I tried to pull in all the other stuff  
as well, which is nonsense) and days to fight with 'make-kpkg' because I could 
not have my kernel named 'ubuntu-3.2.0-31+JFS_TRIM', neither on the command 
line nor in the .config file (CONFIG_LOCAL_VERSION) ...
