Mode "1600x1200" is larger than BIOS programmed panel size

I have a Dell 2001FP monitor (1600x1200), but I just get a fuzzy
1280x1024 with Fedora Core 4.  The higher resolution is on the
pick-list in system-config-display, and if I pick it, the xorg.conf
line gets Modes including "1600x1200".  But, next time X
reconstitutes, it doesn't work,* and when I look in Xorg.0.log, I see
good news followed by bad:

  (II) NV(0): Supported Future Video Modes:
  (II) NV(0): #1: hsize: 1600  vsize 1200  refresh: 60  vid: 16553
  ...
  (II) NV(0): Supported additional Video Mode:
  (II) NV(0): clock: 162.0 MHz   Image Size:  367 x 275 mm
  (II) NV(0): h_active: 1600  h_sync: 1664  h_sync_end 1856
h_blank_end 2160 h_border: 0
  (II) NV(0): v_active: 1200  v_sync: 1201  v_sync_end 1204
v_blanking: 1250 v_border: 0
  ...
  (II) NV(0): Mode "1600x1200" is larger than BIOS programmed panel
size of 1280 x 1024.  Removing.
  (II) NV(0): Not using default mode "1600x1200" (unknown reason)
  [Those last two lines are repeated, appearing a total of 5 times.]

What component is issuing this "larger than BIOS programmed panel
size" message?  How can I explain to Fedora Core 4 that this video
board and monitor really, truly can display 1600x1200?  (They did, in
Windows XP, before I deleted it in favor of Linux.)

The video board is "NVidia GeForce 6800" in a "Dell Dimension 8400"
using "xorg-x11-6.8.2-37" and the "nv" driver, attached to a "Dell
2001FP (Digital)".

* Instead of showing 1600x1200, Fedora Core 4 does something
indescribable, which the programmers probably worked hard on, for
which I greatly respect them, but really I'd prefer the 1600x1200. 
It's indescribable, but I'll try:  I think FC4 shows a 1280x1024
desktop through a 1280x960 viewport, which I can pan up and down to
visit the whole desktop.  1280x960 is the same aspect ratio as
1600x1200, which is such a nice touch that I'm hesitant to complain
about it.  But I'd really prefer true 1600x1200!
