I'm looking into this now, will try to get the build sorted out.

That won't even come close to working. The new mceusb.ko is built using
a relocated and renamed stack. Its moved from drivers/media/IR/ to
drivers/media/rc/ and the core bits renamed from ir-core to rc-core, as
we intend to support more than just infrared. So that new mceusb.ko has
module dependencies on rc-core.ko and friends, instead of ir-core.ko.
