could not reactivate nvidia after fallbacl to floss driver on lucid

[SeanBoran]

Doing Fallback Testing according to
http://xorg.qa.ubuntu.com/qatracker/result/3729/427
week 4
Version: 195.36.08-0ubuntu1

OK:
# Boot with functioning proprietary driver
# Locate the driver's kernel module (nvidia.ko or fglrx.ko under /lib/modules)
# Move kernel module aside (mv nvidia.ko nvidia-backup.ko)
# Reboot
# Verify an error is displayed (or appears in Xorg.0.log, syslog, and/or dmesg) that the video driver kernel module is missing
# Verify system falls back to the open source driver (-nv, -nouveau or -vesa for nvidia hardware, -ati or -vesa for ati hardware)

nvidia-current Cannot be reactivated
# Go to System : Administration : Hardware Drivers
# Verify utility permits reinstallation of the missing kernel module
