couldn't mount some necessary NFS drives.

How is one supposed to revert to runlevel 3 (or even 2) to overcome
this sort of problem?  Is there a grub/boot parameter one can use to
change the runlevel?

Yes.
You can select the runlevel you require at boot time, without a boot cd.

Stop the computer at boot time (when you see the countdown or the grub menu). - just hit a key that isn't an arrow or 'enter'.

It's worth reading the paragraph of text under the kernel list to see what you can do.

In your case:

use the up/down arrows to choose a kernel.

hit A (append)

Add a space and then your desired runlevel (e.g. 2) to the end of the displayed text.

Hit enter to boot.

and you'll boot into that runlevel. This change is non-permanent, so the next time you boot your system it will boot normally.
