[clug] ACPI problems

I'm having trouble getting ACPI to work on my laptop (Dell M60). It is 
set up to go into sleep mode when the lid is closed. This part works 
however when it wakes from sleep the display does not wake up.

I tried the hack that Tridge showed at CLUG of:
chvt 1
echo 3 > /proc/acpi/sleep
sleep 3
chvt 7
This changes the display to terminal 1 before sleep and reverts back to 
terminal 7 after waking so that ACPI plays nicer with X.

I've also disabled the nvidia binary X drivers, as well as having no X 
server running at all, and I've removed unused kernel modules with no 

If I do echo 3 > /proc/acpi/sleep from the commandline (VT1) when it 
wakes up from sleep I can still type and run commands but I can't see 

Does anyone have any suggestions?
