Sorry to say, but it still doesn't work for me:

Did I mention that the destination kernel is not installed
yet?
That symlink is supposed to be supplied not by the kernel package, but
by the kernel header package. For example:
Sure, but the kernel header package is not installed yet, either.
It is derived from the same kernel source tree. The symlink doesn't
exist when the omfs module is built, i.e. the line
KERNELDIR ?= /lib/modules/$(KVERS)/build
in omfs' Makefile doesn't work for make-kpkg, even if KVERS
is defined.
Maybe the attached makefile stolen from the nvidia kernel module
helps? It shows how to compute the KERNEL_SOURCES and
KERNEL_HEADERS variables for both make-kpkg and m-a.
