btw., v2.6.25-rc1 is not affected by this. Gbpages support is a "still
cooking" feature only available in x86.git#mm, destined for .26, and
even there it's default disabled and only available on Barcelona class
hardware. (Some of these bits are upstream already to make maintenance
easier, but they are inactive code.)
