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.
