It probably works only in -current anyhow and is in active development... I'm pretty sure ACPI is mutually exclusive with APM. My current guess would be that Sony tied the Fn-5 support to either ACPI or some DPMS mode that I don't know about, on that model, either to save complexity in the environmental control stuff or something. I use apm on my Sony too. The only problem I have with apm is that Athlon boards with via chipsets (not applicable to laptops) often crash&burn badly if apm is even present in the kernel config (clock runs *real* fast, etc etc). -- Pete To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
