BenQ S73U - no ACPI

[Jan Willies <jan@willies.info>]

Hello,

I got a BenQ S73U and it doesn't support ACPI very well. I got 23 
warnings when compiling /proc/acpi/dsdt with the iasl-compiler, but no 
errors. This is confusing, it should work well cause they are only 
warnings, not errors!
Anyway, Sebastian Lammermann managed to turn all warnings down by 
rewriting the DSDT, but one. Unfortunately the behavior didn't change, 
shutdown is still not working.

The last unsolved warning:

dsdt.dsl  1164:             Method (_OSC, 5, NotSerialized)
Warning  1075 -                        ^ Reserved method has too many 
arguments (_OSC requires 4)

If anyone please have a look at the DSDT, it would be very kind! I'm 
really desperate to get this thing working under Linux.

I mailed BenQ about this problem, they even replied which surprised me a 
bit. They promised to pass the mail to their developers, but I don't 
think it will change something... I reckon I'm not the first one who 
mailed them about that.

PS. If you want a nice office-laptop, apart from the ACPI-stuff, the 
S73U is a good deal for 599€ ;-)
