Yeelong and SiliconMotion driver: asking for developers

Is there a reason that graphics code can not be included in the GRUB2 project with its current license ?
My recollection was that the X11 license was considered "GPL compatible" in the sense that it *could* be relicensed if necessary. Graphics driver code is included in the Linux kernel without relicensing, ie it retains its current X11 license even though it lives in an otherwise GPLv2-licensed tree.
Is there something about GPLv3 which prevents the same approach from being used, or are we just talking about a GRUB2 project rule which disallows "compatible" licenses and requires actual GPLv3 licensing ?

I believe the issue there was that FSF needed some small subset of code dual-licensed to be able to incorporate it into GRUB2, which is
GPLv3 - GRUB2 is very close to being able to be the only boot firmware on the actual hardware PLCC chip of the yeeloong, and of course would load before Xorg.
I don't believe there is any intent to actually try to relicense X; as you are probably aware FSF has in the past helped the X project with licensing issues - http://www.fsf.org/news/thank-you-sgi - and knowing the people involved I sincerely doubt there is any intention to do anything that would splinter the Xorg codebase.
