 sadly, this was not and improvement, none of the devices where attached:
 
 acpi_video0: <ACPI video extension> on vgapci0
 Ignore non-standard device (100).
 Ignore non-standard device (400).
 
 100 is my crt and 400 is my lcd.
 
 good effort, and i will be happy to continue to help you. i have to go to
 work now, but i will be happy to either fix your patch or test any new
 patch u provide
