Thats for my LCD; Turns out the SIS driver doesnt use the GTF timing formula to calculate it's timings. (Theres a "hacked" intel driver which is basically the same SIS driver, apparently)
gtf 1440 900 60
gave my modeline, you could try
gtf 1280 1024 60
or something similar to find a suitable modeline for your monitor... or maybe even a different timing formula.
