Thanks, acpi_call -p '\VBRC' -i n [0-15] work fine, if set 17 black screen :)

And other problems.
1) wi-fi
standart rtl8192cu - not work
change AR5B95 - work n-mode (thanks Adrian Chadd :) need hack BIOS
dev.acpi_ibm.0.wlan: 1 <- read only
hardware switch work, not send mesage

2) sound
 # cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <Conexant CX20590 (Analog)> (play/rec)
pcm1: <Conexant CX20590 (Analog)> (play/rec) default
pcm2: <Intel Cougar Point (HDMI/DP 8ch)> (play)
pcm3: <Intel Cougar Point (HDMI/DP 8ch)> (play)
pcm4: <Intel Cougar Point (HDMI/DP 8ch)> (play)
sound headphones only, if set sysctl hw.snd.default_unit=0 and restart
application, on's speakers (if remove headphones).
Automatic switching possible?
2.2) sound control
in mplayer automatic fine work multimedia key
multimedia key and system mixer, and sysctl not work

xev data VolUP, VolDn, mute (release event similar)
KeyPress event, serial 27, synthetic NO, window 0x1e00001,
    root 0x120, subw 0x0, time 210234226, (623,634), root:(623,650),
    state 0x10, keycode 176 (keysym 0x1008ff13, XF86AudioRaiseVolume),
same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyPress event, serial 27, synthetic NO, window 0x1e00001,

    state 0x10, keycode 174 (keysym 0x1008ff11, XF86AudioLowerVolume),
same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

    XLookupString gives 0 bytes:

3) ACPI work poorly
19    1 0xffffffff81f01000 37c7     acpi_video.ko
20    1 0xffffffff81f05000 330f     acpi_ibm.ko
21    1 0xffffffff81f09000 1fc      acpi_call.ko
# sysctl -a | grep ibm
acpi_ibm0: <IBM ThinkPad ACPI Extras> on acpi0

dev.acpi_ibm.0.eventmask: 134217727
dev.acpi_ibm.0.hotkey: 3353
dev.acpi_ibm.0.lcd_brightness: 0 <- not work
dev.acpi_ibm.0.volume: 0 <- not work
dev.acpi_ibm.0.mute: 0 <- not work
dev.acpi_ibm.0.thinklight: 0 <- work fine :)
dev.acpi_ibm.0.bluetooth: 0 <- work LED (bt not use, not test)
dev.acpi_ibm.0.wlan: 1 <- read only
dev.acpi_ibm.0.fan_speed: 3880 <- not work or read only
dev.acpi_ibm.0.fan_level: 0
dev.acpi_ibm.0.fan: 1

LED HDD may be work blink infrequently SSD :)

3) video work acceptable
WITH_NEW_XORG=true
WITH_KMS=true

from terminal adjustable brightness
acpi_call -p '\VBRC' -i n [0-15]
I would like to consolidate these actions on the standard key # cat
/var/run/devd.pipe
!system=ACPI subsystem=IBM type=\_SB_.PCI0.LPC_.EC__.HKEY notify=0x10 ( Fn+Home)
!system=ACPI subsystem=IBM type=\_SB_.PCI0.LPC_.EC__.HKEY notify=0x11 (Fn+End)

4) mouse Xorg with out config
standard trackpad and other work fine

if hook up USB mouse not work
Jan 27 17:53:23 x220 kernel: ugen1.3: <A4Tech> at usbus1
Jan 27 17:53:23 x220 kernel: ums0: <A4Tech USB Mouse, class 0/0, rev
1.10/0.14, addr 3> on usbus1
Jan 27 17:53:23 x220 kernel: ums0: 8 buttons and [XYZ] coordinates ID=0
and  disconnect
Jan 27 17:53:42 x220 kernel: ugen1.3: <A4Tech> at usbus1 (disconnected)
Jan 27 17:53:42 x220 kernel: ums0: at uhub3, port 2, addr 3 (disconnected)

5) suspend/resume not test while, if there is a manual will be grateful

Trick, to work without xorg.conf :)
# cat /home/andrey/.xsession
/usr/local/bin/xset +fp /usr/local/lib/X11/fonts/terminus-font/
     <- need some applications
xkbset -b
                      <- hate beep
setxkbmap -layout "us,ru" -option "grp:caps_toggle,grp_led:caps"   <-
for two layouts and indication
