Hi,
I have an update on this Dell Precision laptop. I "accidentally" left
the Debian sid repository active when apt-get ran :)
The kernel updated to 2.6.39 and the laptop DOES suspend and resume.
I had to remove the reboot=bios option from the kernel command line
before this success was experienced.
I still have intermittent trouble.
1. Sometimes, suspend fails to shut down the network devices and the
laptop resumes immediately. Manually disabling the networking devices
seems to help.
Running hook /usr/lib/pm-utils/sleep.d/55NetworkManager suspend suspend:
Having NetworkManager put all interaces to sleep...Failed.
2. Often the laptop still refuses to turn itself off. After I try a
command like "/sbin/shutdown -h now" or the menu shutdown options, I
see the black screen messages that halt at "Shutting Down". Whereas
"reboot=bios" did solve that in previous kernels, it does not help
now, and it seems to get in the way of suspend/resume.
Still no success on getting the full functionality of the touchpad,
but you can stop the system from seeing it as a mouse, which helps in
some ways to prevent the mouse-like interpretation of touchpad
behaviors. Here's the link on howto

This does not enable scroll for me, but it does protect the touchpad
from mouse harassment.
