I believe those are Merrifield and Moorefield. gma500 doesn't support
them. However 64-bit Cedarview is supported. The register PSB_BSM is
the base of stolen memory which is set by BIOS. IIRC the SGX only
supports 32-bit addresses so I would be surprised if PSB_BSM would
ever be longer than 32-bits.
