This problem was originally reported here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/754711

The system works correctly with the Ubuntu-patched 2.6.35 Kernel as shipped
with Ubuntu 10.10, but fails with the 2.6.38 kernel from Ubuntu 11.04.

While tracking down this problem, I tested several mainline kernels, all of
which also fail to suspend/resume on this system, as I describe below.

Steps to reproduce:
- try to enter suspend mode (I used sudo pm-suspend)

Expected result:
- The system enters sleep mode and upon pressing the power switch, resumes
successfully

Actual result:
I tried this with the following kernels (all mainline):

2.6.39-999.201104080911 - The system enters suspend mode, but upon trying to
resume, the system is unresponsive: backlight doesn't come on, there is no
display, keyboard is unresponsive, and system doesn't respond to pings on the
network.

2.6.38-3-natty mainline kernel. The system boots and is usable, enters suspend
mode, but upon attempting to resume is unresponsive, the backlight doesn't come
up, no display, keyboard is unresponsive and system doesn't respond to pings on
the network. At some point I saw capslock flashing but it stopped after a bit.

v2.6.35.12-maverick mainline kernel, with this kernel the system boots but when
trying to enter graphical mode becomes unresponsive, no keyboard, network ping
or display (screen is black). 

Here is some relevant information on the system, please let me know if any more
tests are needed.
