No problem --- we have time.

Here's how I would suggest blacklisting the drivers:

	echo blacklist nouveau >/etc/modprobe.d/ls-blacklist-gpu-drivers.conf
	echo blacklist nvidia >>/etc/modprobe.d/ls-blacklist-gpu-drivers.conf

Then choose "recovery mode" from the boot menu so X doesn't
automatically start.  This should get you to a console.  You can
check your work using lsmod.

Then remove the /etc/modprobe.d/ls-blacklist-gpu-drivers.conf file
to return to the previous configuration.

If you want to load one of the drivers for a single boot, the simplest
way is to modprobe it directly.

Add a line for experimental to /etc/apt/sources.list:

	deb http://mirrors.kernel.org/debian/ experimental main

Packages won't be installed from there automatically.  To install
a particular package, pass "-t experimental" to aptitude:

	aptitude update
	aptitude -t experimental install linux-image-3.5-686-pae

Thanks,
