I'm working on Dell's laptop support, even though I'm not

know if such tool under FreeBSD exist).
Some preminaly code can be found here:

Bruno,
Did you make suspend/resume work?
Did you make your volume up/down key work?
I have Latitude D620 and can't make above work.
thanks,
Ganbold
For now, the 3 tar ball above have not been publically send to any
public list I'm aware of, because those are only priminally work.
For [1], people can check I haven't removed any copyright, nor I even
bothered adding my name. In any case, I don't plan to add that one to
the base system.
In fact, I think to remove it from http://people.FreeBSD.org/~bruno/
in the near future.
For [2], people can check it's a really preliminary work, and is based
on some calls to ACPI methods under the DSDT. Since it's a really
different approach taken from the driver found under Linux, it's free
from any GPL'ed code.
Finally [3] is only a userspace tool to control [2].
Since [2] and [3] are free from any GPL'ed codes, I consider commiting
them if one day they work.
Actually I even considered to port [2] under Linux, because this is
the right way to go when ACPI mode is enabled for obvious reason.
The io ports related to the SMM handler are shared, and ACPI take
care to handle an ACPI mutex before entering SMM, that at least might
eliminate strange cases when sometimes i8k doesn't work.
Cheers,
