Hi Michael,
Oh my gosh, what a tremendous amount of work you've done.

Again, I'll volunteer for some polishing on PREEMPT_RT, but need a
little time for other things first.
I found the same thing you did in re. to latency compared with Xenomai.

Compiling the kernel with module versioning support should work fine as
long as the RTAPI/HAL modules are compiled against the exact same
kernel, with exact same symbol versions, as the one they will run with.
That is, if a vendor were identified as a kernel package supplier for
LCNC, one new RTAPI/HAL package would need to be compiled for every
single new version of kernel package the vendor shipped.
This sounds like a headache, but it can be automated, and compared to
the headaches the kernel pkg vendors have (check out the PlanetCCRMA ML
archive for an example of what kind of problems kernel pkg vendors must
deal with), it could be less painful.

Hey, I was just looking for my contact lens under there.
