Any more detail on what the exact nature of the problem is? Black
screen?

One thing Ubuntu does do is quiet boots with splash on by default. You
might want to ask him to press ESC at GRUB and:-

a) See if he can choose "recovery" it boots to a shell.
b) Choose one of his old (pre 2.6.20 [likely to be 2.6.17]) kernel from
edgy (6.10).
c) Select the latest kernel that fails to boot, press 'e' to edit, then
down one line, 'e' to edit again and then go to the end of the command
line and remove "splash" and "quiet" from the line. Press enter, then
'b' to boot and see what it stops at.

Common causes of upgrade failures in the past:-

Change from /dev/hda to /dev/sda, change from /dev/sda to UUID,
installation on older release of dodgy binary video driver direct from
*AHEM* manufacturer, use of dodgy """helper""" scripts to install
drivers/applications {like envy and automatix}, use of apt-get
dist-upgrade to upgrade rather than the recommended use of
update-manager and so on...

I'd say some of that paragraph to him and see what response you get. If
light bulbs go on when you mention some of those things it might help
the diagnosis.

Where abouts is he? Can he live without it until the next meet? If it's
near by I'd gladly go over there for a fixed period of time (say 2 hours
max) in the evening for a small donation to the LUG.

Or you could do it ;)
