 Hi Andriy
 
 Some of old problems is still here.
 I have got today's CURRENT and retested this ACPI stuff again.
 
 - acpicontrol -s 3
 In pure console I can put my notebook in S3 state. After that it wakes up if I 
 press any keyboard key or notebook's power button, but screen (console) is 
 inactive (backlight of the screen is on) and I can not use keyboard. I can 
 get console back by pushing power button one more time, or by pussing 
 Fn+BrightnessUP key combination. After that my touchpad/mouse is still 
 inactive. I can get touchpad back using it's on/off swith (it is connected to 
 USB, and after on/off cicle system find it).
 
 In Xorg (KDE3) I can put my notebook in S3 state. After that it wakes up if I 
 press any keyboard key or notebook's power button, but screen (console) is 
 inactive (backlight is off) and I can not use keyboard. I can get console 
 back by pushing power button one more time, or by pussing Fn+BrightnessUP key 
 combination. After that my touchpad/mouse is still inactive. I can get 
 touchpad back using it's on/off swith.
 
 In both cases sysctl parametr: hw.acpi.reset_video=1
 
 In both cases I can see this error message on console:
 ACPI Error: No handler or method for GPE[0x 6], disabling event 
 (20101013/evgpe-734)
 
 
 - Functional keys (brightness/sleep/mute/volume)
 This Fn keys still don't work nativly. I'm missing brightness control and 
 sleep. All other keys are working now using different "keyboard tools" from 
 ports. I can see that brightness is working while I'm in BIOS, but it stops 
 working just after FreeBSD kernel is loaded...
 
 
 - Battery status
 Looks like that battery indicators works now! I can see from sysctl output 
 mesurments or capacity, remained time and status of power and battery.
