I figured out the clocks for the Ultra Pro, so I'm reposting. Thanks to
BQll C. Riemers for pointing out that the clocks in my last post were
wrong.

bcr: Thanks to Kevin's work we now know the true clock spetds. Since the
bcr: only difference left between our Xconfig files is a matter of
personal
bcr: preferance, I'm merging both of these Xconfig files. I now have
bcr: vgaset working and I was able to make a flicker-free 1152 by 910
mode.
bcr: The vgaset modes are now default.

# These timings are set up for _my_ LB ATI Graphics Ultra Pro with
2MB
# VRAM installed. You may need to do some fine tuning due to variations
from
# card to card and monitor to monitor. These _should_ work on a 1MB card
# without too much modification. Here is a quick and dirty description
# of how to fine tune these timings by modifying the numbers below:
#
# bcr: No modifications are needed for 1MB VRAM at this time.
#
# name - Not really a number, just a label.
# clock - Increase to reduce flicker at higher resolutions.
# You will have to readjust everything if you change this.
# bcr: Higher clock speeds means less flickering. However too high
# bcr: of a clock speed means you won't be able to use your full
# bcr: screen.
#
# horizontal timing -- all numbers are multiples of 8
# 1st - The width of the display (in pixels) -- don't change this
# 2nd,3rd - Increase (the same amount) to move display left.
# Decrease (the same amount) to move display right.
# bcr: X3 just seems to have random effects
# 4th - Increase to make display narrower.
# - Decrease to make display wider.
#
# vertical timing -- numbers do _not_ have to be multiples of 8.
# 1st - The depth of the display (in pixels) -- don't change this.
# 2nd,3rd - Increase (the same amount) to move display up.
# Decrease (the same amount) to move display down.
# bcr: Y3 just seems to have random effects
# 4th - Increase to make display deeper (taller).
# - Decrease to make display more shallow (shorter).

# bcr: I strongly recommend using vgaset. (Found on sunsite.unc.edu.)
# bcr: Any mode with a verticle frequency of about 60Hz or greater should
# bcr: appear completely flicker-free.
