No need to load any firmware manually. It works better when using SYNCDHCP instead of DHCP in ifconfig_wlan0 in /etc/rc.conf.

Installation

Installation works fine from memstick in UEFI mode.

Xorg

Touchpad

Two-finger scrolling does not work out of the box.

I've tried adding the following mouse configuration into /usr/local/etc/X11/xorg.conf.d/10-mouse.conf but without success: 

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "CorePointer"
        Option      "Protocol" "auto"
        Option      "Device" "/dev/sysmouse"
        Option      "ZAxisMapping" "4 5 6 7"
        Option      "Emulate3Buttons" "false"
EndSection

sound workarounds

Might not be necessary on 12.1-RELEASE.
