Thanks for these instructions.   I hoped for a while to get
suspend/resume working on my desktop (Asus P4P8X, P4 2.0).
I've finally narrowed the problem to sk driver (for a built-in
ethernet).  Any attempt to use the network after resume (even
typing "ifconfig") results in a hard lockup, I cannot enter the
debugger from the console.
