Is there any way to do a rough estimate of time needed to render any
given scene when various settings are used with certain computer
configurations?  I.e. can you estimate how long it would take to
render five glass spheres with five point lights over a plane at
resolutions  1600 x 1200   800 x 600   640 x 480   320 x 240
antialiasing on/off
radiosity on/off
CPU 100 mhz  200 mhz  800 mhz  1000 mhz  2000 mhz   6000 mhz

I'm curious 'cuz it'd be interesting to know how fast a scene I
have that took 51:09:07 hms at 700 mhz for 640 x 480 would render
on other machines (without actually trying it on, say, my 486/66)

You could probably get a *rough* estimate by using the ratio of two 
similar machines' scores from the povbench database:
http://www.haveland.com/index.htm?povbench/index.htm

ie, time on computer A * rating of computer B / rating of computer A

You might be able to estimate different resolutions similarly.

Mostly though, no.  There's just too many variables: differences in 
processor architecture & memory bandwidth, different settings for 
radiosity, different jitter _values_ for antialiasing, different system 
load (even from the OS)
