Just tried it out here.
After cp -Ra only a limited part of the kernel rebuilds.
o oiu.c in ieee directory - because it dependson the shell script
o A number of drivers that include version.h
	- This should be changed so local version does not affect
	  the reast of version.h.
o Other stuff that is always build if kernel has changed

Do you use "echo -mylocalver > localversion" to change the local version?
