I've applied your patch, but did some additional changes to it, see

These changes seemed to not be necessary. The RTAI patch applied just
fine with the existing code. If you really think there is a problem
here, please give a more detailed description, but for now, I've
applied your patch without this part.

I've applied this part.
Also, there is a RTAI 4.1 version. Could you look at sending a patch to
use this version instead? It has some patches for much more recent
kernel versions on x86.
Thanks a lot!
