The recent SPL merge caused a regression in kernels with ZFS integrated into the sources where our modules would be initialized in alphabetical order, despite icp requiring the spl module be loaded first. This caused kernels with ZFS builtin to fail to boot. We resolve this by adding a special case for the spl that lists it first. It is somewhat ugly, but it works.
