Not at all. WiFi worked out of the box. However I had to use the i915kms driver from ports as I could get the video working as it was with the previous version of FreeBSD that I was using (I can't recall the version). These are the steps that I had to do after trying many i915kms drivers (both the basic one included and also the ones available from pkg):

1. Get the ports.

2. cd /usr/ports/graphics/drm-kmod; make install

3. Add: kld_list="${kld_list} /boot/modules/i915kms.ko" in /etc/rc.conf

4. Optionally install the `mesa-demos` package and run `glx-gears` to test acceleration.

I think there were some changes to the i915kms driver because the previous version I was using (non-stable) the driver was working absolutely fine. Hope that helps if you're experiencing the same issue!
