Can anyone on grub-devel comment on this? It seems remarkable that we

I'm tempted to ask (but you probably shouldn't try it!*), what if you
clear the BIOS/EFI state (NVRAM) in case it's been corrupted somehow
relevant --
hold Command-Option-P-R while booting

*WARNING! If it doesn't fix the problem, then you obviously still won't
be able to see... and, however it was configured such that GRUB would
automatically be booted is likely to be broken now, leading to
unhappiness :-(
(A safer way to investigate this thought would be to dump the contents
of your NVRAM and upload it and compare it to what the default state
looks like, if anyone knows how to do that?)
Does booting from a Linux LiveCD give you graphics? (via grub or refit
or holding 'c' when you boot) -- both as some sort of failsafe, and it
*might* give us a bit of information. (disclaimer: I don't develop grub2
so far, I just use it [on my Macbook, using grub2 BIOS based since I
haven't gotten grub2 EFI to boot Linux very well yet], and read the
mailing-list)
