FWIW, I've personally built it on 2.6.38 with no problems (that was one
of the first versions of lttng-modules though, it might have changed since).

Someone tried to build it on 2.6.35 but it didn't work out-of-the-box
and they had to backport a couple patches.

Perhaps instead of a straight version check, lttng-modules should check
if some kernel features are available? "lxc-checkconfig" does something
similar for LXCs.
