Not sure why you send this to the platform-driver-x86 list. The platform-driver-x86 list is for things like ACPI/WMI drivers for vendor specific firmware APIs, think drivers like dell-laptop, dell-wmi and thinkpad_acpi. It is probably best if you resend your email to the linux-pci@vger and the generic linux-kernel@vger lists. Regards, Hans
