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.
