Well, I tried to remove all the video mode stuff and just leave the
'vga=790' in the line and then it's back to the crash as noted
before.  True enough, no panic, just a blank screen! Something has
obviously changed with the kernel upgrade from 2.6.31.6 to 2.6.32.2 as
far as frame buffer support is concerned.  I got the suggested video
mode configuration stuff from a grub2 item on the arch wiki.  At least
now I can experiment with different grub entries and keep a good
stable one  available with the latest kernels.  I'm just trying to get
my big screen back <sigh>. See how spoiled we get when something
breaks?:)
