I've never been able to get anyone's "sauce" to combine with an Ingo -rt patch cleanly.

I just usually grab the most recent available clean xsource for which an Ingo patch is available, apply the appropriate Ingo patch, and then copy the Debian stock /boot/config-blahblahblah settings to .config, then I just make oldconfig, taking careful note to enable the RT scheduling and HPET when prompted. Then I just make-kpkg and off I go, i.e.

CONCURRENCY_LEVEL=2 make-kpkg --initrd --rootcmd fakeroot --append-to-version=-foobarbaz kernel_image kernel_headers

And, about 30% of the times the kernel will actually work. When it doesn't, it usually requires turning off HPET or some such thing.
