 I guess for x86 then? Because I don't see a usable patch for 3.8 ARM or
PowerPC, as I wrote below.

 It doesn't make sense to keep RTAI if it is not possible to actually use it.
Your problem shows that it is not usable at the moment. So unless you or someone
else are willing to send patches to fix the issues with it, it makes no sense
for us to keep it around. People who do need it can always recover it from git
history and try to fix the failures.
