Well... except fedora has been doing that for some time, and I expect it 
to show up in RHEL within a couple of years (which is why we've started 
partitioning new systems with 500M or 1G of /boot, instead of 100M).

Oy. I've been doing a good number of upgrades in place, sorta. I take a 
similar box that's already built, then create /boot/new and /new, rsync 
-HPavxz everything except a few things over, make sure to copy over some 
things - ifcfg-eth*, /etc/ssh/ssh_host*, etc, and edit 
/etc/udev/rules.d/70-persistant-net.rules - then invoke zsh, 
files/zmodload (? I'm not at work yet, so I don't have my checklist to 
refer to), then mkdir /old /boot/old, go over and move * old, then 
lost+found, then old/new/*, sync, and reboot. Some times, before I do 
that, I'll rebuild the initrd, if the machine is different than the source.

This way, if necessary, I can go back, and I've got everything still in 
place to refer to or copy.

For your specific problem, not sure what to say. Have you tried pulling 
the keyboard and mouse out, waiting 20 sec, and plugging them back in, 
to see if it would wake up?

Oh, one more question: are you running at runlevel 3 or 5?
