 Well, the topic has been beaten to death here, so you don't really need 
to illuminate me -- it's only due to this popular request I've implemented 
the ability to do 32-bit builds for 64-bit kernel.  I just wonder why 
people insisting on such a setup don't actually contribute some code to do 
that cleanly and keep switching between hacks as they stop working one by

 Having a compiled tree in place these bugs are trivial to track down with 
"find", "objdump", "grep" and some usual shell script magic.
