>Release: -HEAD as of 22-JUN-2011
>Organization:
Lattice, L.L.C.
>Environment:
FreeBSD 9.0-CURRENT #1: Wed Jun 22 14:55:31 MST 2011
root@:/usr/src/sys/i386/compile/AO751h i386
(-HEAD as of 22-JUN-2011; this is a custom build but this is reproducible with GENERIC as well.)
>Description:
The Atheros driver correctly picks up the presence of the card, and we can attach it to wlan0:
ath0: <Atheros 5424/2424> mem 0xd0000000-0xd000ffff at device 0.0 on pci3
ath0: AR2425 mac 14.2 RF5424 phy 7.0
wlan0: Ethernet address: 00:25:56:0c:4e:88
However, since the card is not actually powered on (soft power switch that does not work under FreeBSD), we can't use it -- scan results (either via ifconfig or wpa_supplicant) in:
ath0: device timeout
ath0: device timeout
ath0: device timeout
ath0: device timeout
ath0: device timeout
ath0: device timeout
Additional information:
Kernel config file: (reproducible under GENERIC as well)

>How-To-Repeat:
Take any soft WiFi power Acer netbook or notebook, add FreeBSD (-HEAD is probably required since the ath driver in 7.x and 8.x did not work without patching.)
>Fix:
Works under Linux 2.6, using the acer-acpi module:
http://repo.or.cz/w/acer_acpi.git/tree
Card is automatically powered on boot under Linux 2.6.x kernels, and functions correctly, using that module.
FreeBSD has an ACPI-WMI module now, as well as ACPI modules for other vendors, and appears to just needs an implementation of the Acer bits.
I am available for testing.
