On my iBook (beginning 2004) it works just perfectly, and I don't use any
scripts or unload any module before sleeping it.
Just close the lid and forget about it.
On wakeup my bcm43xx module is still alive and kickin' if I stay in the
range of the AP I was connected prior to sleeping.
What is triggering your suspend-to-disk ? Is that powerprefs ?
Maybe you should report the output that appears on the screen when you
wake up the machine and see if something is wrong.
Here is a typical message I get from my tens of trials this evenining.

Ouf ! Next time I will have to try another way to get this message
(better than retyping it....netconsole ?)
That was what I get when I invoke hibernate, or echo "disk" >
/sys/power/state from the command line.
I have no idea what all these symbols mean. Can anyone explain to me
what happened ? Is the problem hardware-related ? Suspend-to-disk is
supposed to use my swap partition.
Thnak you in advance for your help.
Cedric
