What XF86Config did you use?  The docs at 
http://www.linux-thinkpad.org/bm/tp770x/XF86Config say that the 
appropriate part of the Monitor section goes like so:
    
  HorizSync    30-65
  VertRefresh  50.0-70.0
  Modeline "1280x1024"  110 1280 1328 1512 1712 1024 1025 1028 1054
# NOTE: Modeline should not be necessary if you're using X 4.n, as you 
# should be.  X 3.6 is really old, even for Debian.

...and you need to have the following in the Screen section:

Section "Screen"
    Driver      "trident"
    Device      "whatever"
    Monitor     "whatever you called it"
    DefaultColorDepth 16
  Subsection "Display"
      Depth       16
      Modes       "1280x1024"
  EndSubsection

That only works when you have multiple Modes defined in your XF86Config.  
You can get the same result by doing "xvidtune -next" from the command 
line if your NumLock is being annoying (as it often is on Thinkpads.)  
I use "xmodmap -e 'keycode 77 = Num_Lock' " on my Thinkpad A22p to get 
NumLock working properly.

Maybe.  Look at your Modes and make sure "1280x1024" is listed, if it 
isn't, then put it in.  HTH,
