I would say its because the driver (or at least the compression module used by the driver) has been removed from the kernel. It was removed a while ago because the compression module was a precompiled non open source binary driver. It was then reintroduced because it was reverse engineered. It has since been removed a second time because the the reverse engineering of the driver wasn't a clean room reverse engineer of the driver. So in short its because of issues with the binary part of the driver its basically been removed pending a rewrite. Regards Peter
