Good point.

Then perhaps the following we can do:
 - add a static boolean flag
 - add __init function where we check either PCI root bridge ID or CPU
ID (I don't know which one is better, I suppose second one, though it
will require an update of arch/x86/include/asm/intel-family.h)
 - add a check into the function.

What do you think?
