I tried installing the grub-pc_1.97+20091125-2_amd64.deb and grub-
common_1.97+20091125-2_amd64.deb packages to see if that would help but
the results are the same.  It takes ca. 9 seconds after the Grub
loading... message before the grub menu appears.  And then there is a 5
second countdown to boot the default entry.

I agree that the delay in Grub2 has something to do with the raid setup.
In Grub Legacy I booted hd0,0 (hd0,1 in Grub2 language) rather than
doing insmod raid, insmod mdraid, insmod ext2 and then setting root to
(md0) before booting.  I know that it is more elegant to boot a raid
system in a way that the remaining good disk boots if one fails.  But I
personally don't mind just resetting the BIOS to boot off of the
remaining functional disk if one of them fails.

How can I convince Grub2 to point the MBR to only one of the disks in
the raid (hd0,1 for example)?  And would that possibly speed things up?
Or am I out to lunch here (very possible).  Does the code in the MBR
actually load the modules and boot (md0)?  OR does the MBR on the disk
selected by the BIOS for boot, just jump to /boot of the same disk and
then the modules get loaded etc etc.  I have to admit to being somewhat
confused on these points.
