["Cian Duffy" <myob87@xxxxxxxxx>]

If the module is KDL'ing your box on boot, something is seriously wrong 
with either the bus manager or your box's BIOS. I have been using the 
Haiku ACPI bus manager for some months now to change backlight levels 
on my Sony Vaio R600-HMPD, without any ill effect. Otherwise the 
backlight comes up at level 0 (extremely dark) and  makes BeOS 
extremely hard to use. 

Again, if its crashing, somethings wrong and should be investigated to 
be fixed.
