<< My daughter, who is away at college, called today complaining that her 

iMac's screen is flickering. She has an older iMac (with CRT), indigo I 

think--either 2000 or 2001, OS 10.2.6, 384mb. >>

Hello,
Please ask her if she is also hearing any occasional 'popping' or 'hissing' 
noises.  If so it may be the AV board -specifically the flyback transformer on 
that board. If that is the case sooner or later the screen will go forever 
dark and she won't be able to boot up - so make sure to back-up anything 
important ASAP.  
This is apparently fairly common in the older Imac's, as I learned.  It 
happened to my Bondi blue IMAC a year ago.  It is an expensive repair but there are 
places that will sell you a refurbed board for less. I think I paid around 
$120 for mine. Of course then you need to find someone to install it.
Best of luck,
Val
