This is what I love about X...  I've received several different, 
mutually contradictory, answers.  One gave explicit numbers except for 
one value, which was suggested were likely in the 60-80 range.  This 
answer says it's more likely to be around 160.  (Aside: this line 
appeared in the log -- does that support the 160 hypothesis?)

(II) VESA(0): clock: 162.0 MHz   Image Size:  367 x 275 mm

That aside, the definitive answer was filled with magic numbers whose 
origins I don't know.

Another person said to use 'gtf', but noted that it might not work with 
my card/driver.  And a fourth said it was hopeless with XFree86, and 
that I needed X.Org.

I love X...

Anyway -- my thanks to all, and I'll try these suggestions tomorrow or 
Friday, when I'm next at the machine.
