Seems to me that you may have to calculate a modeline for your display and a site similar to this one could help. I had to do some of this on my HP Z%5000 laptop with 1600x1050 resolution. http://koala.ilog.fr/cgi-bin/nph-colas-modelines I am not sure this is the site I used, and I also consulted various other laptop web articles out there to help me get my video going. I'm not so sure this will be a big helpful answer for you... Might steer you in some direction.
Tks
I did it actually using the same thread.

How come I get the message "no mode of this name"?
The program worked great on my Acer Aspire 1642 WLMi running Mandriva 2006, which has a native resolution of 1280X800. I've been searching for this fix for weeks!
I'm a bit of a novice linux user, so excuse my ignorance with these concerns:
1.Why do I lose this screen size/resolution match every time I reboot? In other words, the screen is "too big" for the monitor upon rebooting, just like it was before I found this fix.
2.The follow up is of course this: how can I keep these settings upon rebooting? If I have to run this program every time at reboot, how do I set this up?
In any Linux distro there's a file that executes custom commands and scripts at boot time.
In Slackware, that file is:
/etc/rc.d/rc.local
If you put:
=============================================
# To change the resolution to 1280x800
855resolution 3c 1280 800
=============================================
in it, it'll execute that command everytime Linux boots.
Therefore afterwards your resolution will always be set at 1280x800.
