The attached file is a draft stub driver for poulsbo. Like you said, it
will only call acpi_video_register and acpi_video_unregister when
initial and exit.
And I added the Poulsbo pci id in the module alias.

It's works to me, where can we put the driver? in driver/staging ? or
put in driver/gpu/stub ?


Thank's a lot!

#include <linux/module.h>
#include <acpi/video.h>

static int __init poulsbo_init(void)
{
	printk(KERN_INFO "poulsbo: stub driver load.\n");
	return acpi_video_register();
}

static void __exit poulsbo_cleanup(void)
{
	acpi_video_unregister();
	printk(KERN_INFO "poulsbo: stub driver unloaded.\n");
}

module_init(poulsbo_init);
module_exit(poulsbo_cleanup);
