Actually it is already possible:

Our autobuilder built and  builds all current stable kernel versions.
The post 6.6 ones with patches on top (see e.g. [1]), like for mainline.
The stable kernels are also run-tested with Ski, which only requires a
few extra patches post linux-4.19.y depending on version ([2]). Also we
follow glibc and make it "work" for us ([3]).

[3]: https://github.com/linux-ia64/glibc-ia64/

I hope I can get qemu-system-ia64 working in GHA in the future, so we
can also run-test non-Ski kernels there.

Mainline is also tested weekly (most of the time) on real hardware
([4]). So stable kernels post 6.6 always start in a working state. I
believe I even tested the older ones at least once on real hardware,
too.
