AMD ACPI interface may overload the standard event ACPI_VIDEO_NOTIFY_PROBE (0x81) to signal AMD-specific events. In such cases we don't want to send the keypress (KEY_SWITCHVIDEOMODE) to the userspace because the user did not press the mode switch key (the spurious keypress confuses the DE which usually changes the display configuration and messes up a dual-screen setup). This patch gives the radeon driver the chance to examine the event and block the keypress if the event is an "AMD event".

Looks good to me, but I'm certainly not an ACPI expert.
