Oh good. :-) I have not tested this, but generally, most user-space
programs are not especially fussy about kernel versions, especially
not minor versions. The exception can be graphics drivers, but if
you're upgrading, your old drivers linked to the old kernel should
still be present. In theory.

If you are using a FOSS graphics driver, then there should be no problem.
