Required tweaks:
• Xorg autodetection with 2.6.37 ( with 2.6.35 only vesa @1024x768 works correctly ) ( 1366x768, +XVideo )
• WiFi - brcm80211 driver, available from staging in 2.6.37 ( alternatives exist for older kernels )
• backlight - requires samsung driver and restart ( available for example from deb http://ppa.launchpad.net/voria/ppa/ubuntu maverick main)
• /proc/easy_slow_down_manager

Out of the box:
• suspend/resume
• ethernet eth0
• webcam (?) @ 640x480
