Something like the following. Note that version_filter requires macro
KERNEL_PATCHVER from target makefile which I assume is not available
at dump time, but this should work at ipk packaging time.
diff --git a/include/kernel.mk b/include/kernel.mk
index 38613756c7..19ecf4fa9a 100644
--- a/include/kernel.mk
+++ b/include/kernel.mk
@@ -259,7 +259,7 @@ $(call KernelPackage/$(1)/config)
endif
$$(eval $$(call BuildPackage,kmod-$(1)))
- $$(IPKG_kmod-$(1)): $$(wildcard $$(FILES))
+ $$(IPKG_kmod-$(1)): $$(wildcard $$(call version_filter,$$(FILES)))
