You gain a few additional sysctls to play with: 

fk at TP51 ~ $sysctl hw.acpi.video
hw.acpi.video.lcd0.active: 1
hw.acpi.video.crt0.active: 0
hw.acpi.video.tv0.active: 0
hw.acpi.video.out0.active: 0

If you need them is another question, at least for
me the defaults are ok and I never changed them.

I always assumed acpi_video was somehow needed to get
suspend/resume working, but at least the man page
doesn't back up this assumption.
