You don't have a dvi-cable handy (assuming you have dvi-out on gfx card)?
There could be some problem with the converter. Normally X, via the gfx
card can probe the monitor with the EDID protocol.

Check the pin-outs of your converter here (to see if its missing the
needed pins):

It is strange, however if another driver (vesa or radeon?) works. Seems to
suggest a driver bug...

There is one more thing you could try:

# ### FireGL DDX driver module specific settings ###
# === Screen Management ===
    Option "DesktopSetup"               "0x00000000"
    Option "MonitorLayout"              "AUTO, AUTO"
    Option "IgnoreEDID"                 "off"
    Option "HSync2"                     "unspecified"
    Option "VRefresh2"                  "unspecified"
    Option "ScreenOverlap"              "0"

You could try setting IgnoreEDID to "on" and put back your monitor
H/V-values. It may be that the IgnoreEDID setting makes the driver probe
the monitor even if you have specified H/V values and the monitor either
supplies wrong values or the driver screws them up.
