Hi,

controlling brightness works for me (via shell) - taking matt's advice
into account:
> \VBRC seems to allow control over the backlight, at least, so those of
you with sore eyes or the 3-cell battery may have some success using the
acpi_call port (Danger!)
> kldload acpi_call
> acpi_call -p '\VBRC' -i n (where n is 0-16; 17 (and -1) is off)


Cheers,

Hannes
