I had a similar problem last week. After an update, the intel driver stopped
working and xorg used the vesa driver instead.

I then found out that the i915kms wasn't loaded automatically anymore.
All how-to articles warned "do not add the module to loader.conf, because a failure
may render your system inoperable. Instead add the module to /etc/rc.conf".

I tested the module with kldload and it worked, so I added the module to rc.conf
("kld_list="i915kms") and everything was fine.
