Description of problem:

1. as root # echo 'mem' >/sys/power/state

The laptop power led and (blue) wifi led switch on, the hdd activity led lights
up for a while, the screen remains dark, there is no response to the keyboard.

I can confirm the same behaviour on my nc8230

I installed the new kernel
$ uname -a
Linux goedel.home.rtfm.gr 2.6.18-1.2200.fc5 #1 Sat Oct 14 16:59:26 EDT 2006 i686
i686 i386 GNU/Linux
but I have the same symptoms with the new kernel
After further testing, when suspending with the proprietary ATI driver kernel
module, on resume the keyboard responds (Caps lock works - Alt-SysRq- Reboot occurs)
However no video output occurs
Unfortunately, there's rarely anything we can do with proprietary drivers.
You may be able to coax it back to life with some magical incantation of
vbetool, but it's completely black magic.
Good to know the keyboard is back though. I'll close this out, as there's
nothing further we can do.
Without the proprietary drivers I don't even get this far.....
No keyboard no screen
