I experienced a similar problem on an older Nvidia card. If you want to
get the old behavior back, create a file in /etc/modprobe.d with an extension
of .conf. For example: /etc/modprobe.d/local.conf. Then turn off kernel
mode setting with a line in this file that looks like this:
options nouveau modeset=0
This will give you the hardware text-mode video modes on the text consoles
(1-6 by default) as before. Then, as root, run
against the 2.6.32-5 initial RAM file system. Then, shutdown and reboot.
The nouveau video driver in X won't work if the nouveau kernel module doesn't
do mode setting. This should get your nv driver back. Blacklisting the
nouveau kernel module might work too, but using modeset=0 as an option was
how I solved it. (Make sure that /etc/modprobe.conf does not exist. If it
does, then files in /etc/modprobe.d will be ignored.)
