No, it was waiting for RTAI providing its Module.symvers and a patch like yours.

The true solution is to drop support for legacy kernels and for setups where the realtime extension is not installed together with all Linux modules (or is not already part of the kernel) and completely switch over to kbuild. RTnet's way of using autotools for kernel modules is no longer state of the art, used to be a maintenance PIA right from the beginning, is slow to build (it does not scale along make -j) and was only due to the limitation of kernel builds we had to deal with in the past. But for this RTnet series we still have to keep the legacy. So I ran an update script and switched to kbuild's clean for RTNET_KBUILD_CLEAN. Thanks, Jan
