After kernel update and reboot, the display only shows a resolution of 800x600,
while the vesafb detects the full resolution. Some syslog messages:
kernel: vesafb: mode is 1680x1050x32, linelength=6720, pages=0
kernel: NVRM: loading NVIDIA UNIX x86_64 Kernel Module 340.96 Sun Nov 8

kernel: NVRM: Your system is not currently configured to drive a VGA console
kernel: NVRM: on the primary VGA device. The NVIDIA Linux graphics driver
NVRM: requires the use of a text-mode VGA console. Use of other console
NVRM: drivers including, but not limited to, vesafb, may result in
NVRM: corruption and stability problems, and is not supported.
