Would you mind sharing what you did to get it to work and the 
/etc/acip/actions scripts with me?

When I do a sleep (suspend to RAM) it shuts down (backlighting doesn't 
go off but don't think it's that important yet) but wont start again, 
I have to hard reset, unplugging the power and removing battery. Also, 
since I have enabled acpi I have had random system lockups when the 
laptop just stops responding to mouse/keyboard and have to power off 
again.

Any pointers would be great fully accepted, once I get it right I'm 
putting together a dummies how to.

This is what I've done so far for X24 Mandrake 10.1:

enable the hotkeys and play a little with things:

copy laptop_mode & idectl to /usr/local/sbin/

create file "/etc/acpi/event/lid" with the following:
event=(button/lid|ibm/hotkey HKEY 00000080 00005001)
action=/etc/acpi/actions/sleep.sh

add "ibm_acpi hotkey=enable" to /etc/modprobe.preload for module to 
auto load on boot
(note modprobe.preload is for kernel 2.5 or later, earlier kernel use 
/etc/modules)

add acpi_sleep=s3_bios to kernel paramiters in lilo.

I've also turned off apmd and apic but seem to need apicl for kernel 
to boot past "Calibrating delay loop..."

Begining dmesg=
