Mmm. It seems acpi_video_bus_check() is static and therefore not

BTW. I'm curious what you are trying to do.
There is actually quite a bit of movement in this code right now.
Think about fbdev drivers (or some video driver).... Rather than
bang on the hardware to try and do auto-detection of devices, it's much
easier (and sometimes required) to just ask the system BIOS via ACPI to
see what devices are available.
I want to parse _DOD myself to see what's available in kernel space.
It would be good to have this code in only one place
and export it from there to other parts of the kernel that need it.
I'd like to be able to not have fbdev drivers depend on the acpi video driver,
so perhaps we could have some generic interface where fbdev is the consumer
and in this case acpi/video.c is the provider?
There is module autoloading code in acpi/scan.c which might be helpful.
Just look for acpi_video_bus_match().

Alex.
