See if loading acpi_video(4) helps.

SirDice means that you should try kloading acpi_video, i.e. # kldload acpi_video.
The MIB (SYSCTL) variables mentioned in the man page (acpi_video(4)) can be read and modified using sysctl(8), e.g. # sysctl some.sysctl.variable and # sysctl some.sysctl.variable=some_value respectively.
