Is this no longer true on the latest? PowerVR does - i740 never did. The PowerVR 0xfc poking also doesn't currently work once the driver takes over because it isn't yet implementing the driver end of the weird ACPI messaging/event stuff. Once it does the GMA500 will be able to do an ACPI video register, but we will still need the check to get the ifdeffery right for what drivers are compiled for the kernel.
