Martin,

the code in kernel.bbclass does already copy defonfig to .config, see
http://cgit.openembedded.org/openembedded-core/tree/meta/classes/kernel.bbclass#n216

I think your problem is the deconfig is not found,  you miss a colon at the end.
Use something like

FILESEXTRAPATHS_prepend :=
"${THISDIR}/${PN}-3.4:${THISDIR}/${PN}:${THISDIR}/files:"

Cheers

Andrea
