It's totally at the whim of your BIOS I believe :(

Those ACPI video patches worked here ->
[chowder 11:08] ~/projects/acpi_vid-20031013 >sysctl hw.acpi.video
hw.acpi.video.crt0.active: 0
hw.acpi.video.lcd0.active: 1

Although if I turn off the LCD by setting it to 0 it wakes up when I press a 
key, but the sysctl remains set to 0.
