OK, so we know that the driver somehow screws up switching to VGA mode,
but at least it has no problem switching back to X and it does not
crash your system.

(This is not relevant for tracking down your present problem, but it is
 handy to know in case of "hard" lock-ups.)

This is harmless; you can remove the "type1" line from your

AFAIK, this is an unrelated minor bug.

No real clues so far; what do you get from the following three commands?

lspci -nn | grep -Ei 'vga|video|display|graphic'

lsmod | grep -E 'agp|fb|nvidia'

grep -Ei 'vesa|nvidia|frame|buffer' /var/log/syslog
