Good to know !
I´ll install FreeBSD 8.0 tomorrow and give your driver a go and as
soon as I have something, I´ll report back to you :)

That´s even better than I expected because bwi(4) simply doesn´t
support my hardware!

So what shoudl I do?
Load it alonside bwi(4)?
Just load it and see what I get on /var/log/messages and dmesg and report back?

And since you are writing a new driver, can I help to make it work
with ACPI from the get go?
