Comment:
I too have a Dell XPS Gen 2. It has resume=/dev/sda2 in the grub config.
apmsleep -S 08:00 returns apm support isn't in the kernel.

Calling /etc/acpi/sleep.sh manually fails which I think is because
/usr/share/acpi-support/Dell Inc..config doesn't have the model
"Inspiron XPS Gen2" in it, if that's significant?

Choosing System --> Logout --> Sleep from Gnome menu causes the system
to shutdown with the power light blinking slowly (fade up/down). Tapping
the power button to wake it up fails. The power light comes on, 3
seconds of disk activity, then a blank screen and nothing, no bios
flash, no console messages. Holding down the power button down for 5
seconds to shutdown does shut down fully. Tapping the power button
causes the usual BIOS splash, grub menu, ubuntu startup sequence to
happen.

If I switch to a console and issue "sudo /etc/init.d/gdm stop" then
"sudo su" then "echo 4 > /proc/acpi/sleep" the laptop appears to do some
suspend type activity then shutdown. If i press the power button I get
BIOS splash, some suspend reading from disk activity, then a few ACPI
messages, then a reboot. It then starts normally to a gdm prompt.

Hope that helps.
