Yep, IIRC they don't work because they are loaded at an address that is too far away from the relocation range of the bl instruction, so calls from the module back into the kernel fail.  A new feature is being added to gcc-3.0 for the ARM to force long-calling (always call through a pointer), this should solve the problem.
