Watch out. It did fix it for me but only after a deep
clean. (mrproper) Makefile does not pick up this dependency.

Also I could not use my 2.6.34 config file. I had to do
make defconfig, and then xconfig all my extra stuff. But
this is regular for any Kernel upgrade and UML.

It does fix my setup. (Wouldn't load before this)
