There's nothing said about GRUB or Linux in his mail - since he didn't 
go into detail on what he's planning, for all we know his project might 
be fundamentally incompatible with EFI, "Unified" or not.

Anyway, reasons why UEFI might not be suitable for users (no matter if 
GRUB or not):
- The IBVs's track record in product quality is rather mixed (Samsung's 
UEFI variable issue, for example. More examples: all the BIOS 
workarounds within Linux)
- IBV's products aren't open source
- UEFI's footprint is at least five times that of a coreboot solution in 
terms of lines of code (yes, I measured it)
- the previous two issues make any quality and/or security assessment of 
UEFI solutions harder than of a coreboot solution

I didn't think that these types of arguments need any more mention on 
the coreboot mailing list, but here we are...

Yes, and Google's "best effort" only had to happen because Intel isn't 
willing to support their customers' wishes.

"locked IPS, sole property of INTEL" is probably not a very appropriate

Since nothing but whitepapers is published on FSP yet, this can be 
safely considered vaporware.

Maybe you can figure out a schedule for when we can expect an FSP binary 
that we can host in our 3rdparty repository under the same terms as the 
current MRC binaries?
That is, if FSP ever gets released at all (even Duke Nukem Forever did 
eventually happen, so let's hope)
