I checked pre and post upgrade and debconf-show grub-pc is identical.
I didn't reboot the box, I just updated the package again, run what you
asked and downgrade grub again.

If there was something wrong with the configuration I'd guess just
downgrading wouldn't solve the problem.

This is the first grub upgrade that has been made on this box and
nothing was changed from installation.

As you can see it runs on a RAID1. There are just 2 partition: / and swap.
I can spot a difference between this non booting box and a box that boot:
GRUB_CMDLINE_LINUX_DEFAULT="quiet" # not booting
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.dpm=1" # booting

These are 2 very different machine in terms of partition layout etc...
still the message was related to "color" that make me think "splash"
could be an interesting difference.

Sorry if I didn't take note about the exact error. If you need the exact
missing symbol I'll upgrade again and reboot the box ASAP (a couple of
days).

thanks
