The errata text says "This enhancement requires the kernel-3.10.0-140.el7 version or later to function properly. (BZ#1122130)", but no such kernel seems to have landed yet. Is it a problem to run this build with the older kernel, or is it just that fixing this issue requires both?

There are bits in kernel allowing userspace driver to work properly. Closest window for kernel update is 16.9.

autoconfiguration of the driver requires both components. Without the updated kernel, the synaptics driver simply won't do anything though a user can set up configuration files to get the new behaviour. This isn't recommended though as the new kernel also fixes some hardware reporting issues.

It is safe to run the updated synaptics driver on an older kernel.
