This didn't work unfortunately.

The problem is actually a bit weird. When I suspend (close the lid or with
the key combo) the display is not turned off actually. It does go in some
form of suspend however. When I resume, the machine comes back to life
again, but the screen goes off at that moment. 

One other note: 

At boot time the VGA is reported as:
Aug 25 21:15:20 laptop kernel: vga0: <Generic ISA VGA> at port 0x3c0-0x3df iomem 
0xa0000-0xbffff on isa0

And when I load your module:
Aug 25 21:12:44 laptop kernel: vga_pci0: <Generic PCI VGA> port 0xc000-0xc0ff mem 
0xfcff0000-0xfcffffff,0xe0000000-0xe7ffffff irq 11 at device 0.0 on pci1

In other words, is it a problem that it is already configured as an ISA
device or is that normal?

Ah, that makes sense. I was searching through the acpi documentation and
couldn't find anything about displays actually. So this is fully
controlled by the graphics controller?

I also have an ATI chip. ATI Radeon to be precise, is that a possible
