12.04 upgrade broke grub? (not wubi related)

I just updated from 11.10 to 12.04, with no major problems (it took a while to get past a request to restart ssh, mysql and some other services, but I did no fiddling by myself, everything was done by the installer). However, after restarting, grub can't do anything. Picking the new linux installation… >>> More

Will final version of 12.04 use the power management changes found in kernel 3.3

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.
