Finally got a chance to do a fresh build. This simple patch now pulls in custom
device-specific kernel patches at kernel-header build time, as you suggested.
However, it differs from target/linux26.mk where the patch files are not
filtered by "linux-$(LINUX_HEADERS_VERSION)*".  Not sure if this will affect
other builds.
