[Workaround] As workaround add the option i915.powersave=0 to the kernel command line in the grub config (for GRUB 2: edit /etc/default/grub and add i915.powersave=0 to GRUB_CMDLINE_LINUX, then run sudo update-grub; for GRUB 1: edit /boot/grub/menu.lst and add i915.powersave=0 to the end of the line beginning with # kopt=, then run sudo update-grub).
Ethernet
This model comes with an Atheros AR8132, supported by the atl1c module. It works fine with squeeze's kernel and on lenny since 5.0.5.
atl1c is included in the mainline Linux kernel as of 2.6.29. The driver was backported and enabled in linux-2.6 2.6.26-22,
