Case 4) grub not able to load kernel. This was because I had
chosen /boot to install grub on, rather than /dev/sda.

I know have two systems upgraded to squeeze and using grub2,
one 32-bit PIV and the other a 64-bit Xeon machine.

That seemed really worrisome to me as well, and I still haven't sorted
out the problem of managing services on Debian. Not sure which toolset
to use: sysvconfig? update-rc.d?

    So far for me as well, except that I have to reconfigure X on the
64bit machine.
