I just did another
sequence today, and I find that the solution listed above is no longer complete.
I find that I now must specify
driver = "nv"
in the "Device" section of /etc/X11/xorg.conf to get the nv driver back.
The nouveau X driver now apparently works even if modeset=0 is specified
as a nouveau kernel module parameter. I also found by experimentation
that blacklisting the driver does not work. The nouveau X server
explicitly loads it. You must explicitly specify the nv driver in
/etc/X11/xorg.conf if you want to use it instead of nouveau. But
specifying modeset=0 as a kernel module parameter does seem to get the
hardware text video modes back on the text console, even if the nouveau
driver is used by X.
