Vostros lose video (and possibly everything?) on auto-upgrade

[jdreed]

When the Vostros attempt to auto-upgrade, they lose. They sit either at a pixelated, inverse-color Plymouth screen or just sit there with scrambled lines on the top 1/3 of the display. Something is clearly working, because they continue to ping at least for a bit, and switching between VT1 and VT2-6 causes a slight change in the video pattern. I think we need --reset-vga for kexec (the manpage is unclear whether this is passed at load time or exec time), or we need to pass vga=mumble to the new kernel?

Regardless, the install works, so if we have to install Stata by hand, we can deal, but this needs fixing.
