status "Ingo's Real-Time" patch

Does anybody already (successfully) use "Ingo's Real-Time" patch for PPC.
It can be found here:
http://people.redhat.com/mingo/realtime-preempt/

We tried applying an older patch for the 2.6.19 kernel on a MPC870 board, but it failed to compile.

Thanks,
N.

Hello.

I don't know about the status of 2.6.19 RT patch, but we're successfulyl
using earlier patches with some add-on -- for example, timeofday syscalls calls are broken in the stock RT patch causing glibc to return imprecise / incorrect time... Look in the linuxppc-dev archives for the extra patches I posted that hadn't gotten into RT patch still...
