I suspect this will break other machines. Not all video extension implementations are directly associated with the PCI ID. The Toshiba M200 (for example) has Device (PCI1) { Name (_ADR, 0x00010000) Device (VGA) { Name (_ADR, 0x00) which will result in VGA not having a physical device. You might be able to get away with walking the parents until you find a pci ID and then checking whether it matches the graphics adaptor, but I'm not certain of that. To make things more entertaining, Dell tend to implement a video extension for both the 00:02.0 and 00:02.1 devices on Intel systems. We need to be smarter about this, but I don't think simply looking for a physical device is the solution. -- Matthew Garrett | [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
