     Bzzzt!  Please do not send innocent victims into the hal nightmare.
That package is *not* needed and *should be avoided whenever possible*.

     Yeah?  Good luck with that.  One it has the graphics device, I
doubt it will allow itself to be unloaded.  A reboot will most likely
be necessary.

     It shouldn't be necessary to load drm.ko manually.

     There can be problems with the above method of loading this, IIRC.
Using

kld_list="/boot/modules/i915kms.ko"

in /etc/rc.conf.local (or /etc/rc.conf if you don't separate your own
added choices from the system's) is the preferred method.

     Note that manual configuration should be used only as a last resort.
Most users should let xorg autoconfigure unless there is a problem in
getting particular devices, fonts, drivers, etc. recognized or for special
screen, keyboard, and/or pointing device setups.

     True, except for users who run -RELEASE GENERIC.

     Not true AFAIK.  I don't do that, and it works just fine.

     Yes, this one most likely does need to be specified for Intel's
integrated graphics.
