X 4.3 on thinkpad iSeries 1300

[karl agee]

Trying to get X running (correctly) on a thinkpad iSeries 1300.  This unit has 
a silicon motion LynxEM+ video chip and a 800x600 svga display.

I can get X running, but, it comes up only in 640x480.  Additionally the 
display looks like it is displaying in a 1024x768 mode as all of the fonts, 
graphics, etc are very_large scale.  

any tips to getting things setup straight appreciated.
