I did a fair number of updates last night, including KDE 4.2 packages
and 'kmod-nvidia-173.14.15-1.fc9.10.i686'.

Normally, when I there is a problem with kmod-nvidia, X crashes right
away. However KDM seems to work just fine. But as soon as I log in,
the loader win comes up, then the monitor flickers (suggesting that X
restarted)

The end result is that I couldn't log in to KDE this morning and was
too busy to create a new user. I have a secondary 'guest' user on the
same machine, but that account couldn't log in either.

So I am debugging this remotely (no X).

So I would like a suggestion on what to do about this. I didn't have
similar problems on my updates-testing machine, but it may not have
the same kmods.

Last time I tried to switch back to nv, i basically couldn't. So if
that is going to be a suggestion, could some one let me know how to
disable desktop effects from the command line? KDE simply won't
startup with nv last time i tried.

Dont know what grahics card you have but during the f9 release nvidia split geforce5(FX) support out of the main driver package so kmod-nvidia refers to the old driver that includes geforce5 support. If you have a geforce6 or higher then switch to kmod-nvidia-newest for the 180 series driver.

This doesnt apply to f10 but i mention because you appear to be using f9. Apologies if you already knew
