Notes

The ALPS/2 touchpad is not recognised by default, works in PS/2 emulation mode. No two-finger scroll or right-edge scroll. A kernel patch for Debian and Ubuntu is available from http://people.canonical.com/~sforshee/alps-touchpad/ ; (it is reportedly already included in Fedora 16).

XVideo output suffers from serious tearing. Use “mplayer -vo gl2” (no tearing) or vlc with vaapi (moderate tearing).

Setting “i915.i915_enable_rc6=1” on the kernel command line dramatically improves battery life.

The machine has ACPI issues that cause low battery life. See http://thread.gmane.org/gmane.linux.acpi.devel/51291 . This is worked around by kernel 3.1.5, which increases the battery life somewhat.

Summary

Run kernel 3.1.5 or later, set “i915.i915_enable_rc6=1” in your grub configuration, apply the psmouse patch, and play video using “mplayer -vo gl2”.
