Is this the siemens board? (the most common tseng et4000w32p out there)
Anyway, stg1703 is broken on 640x480 and 800x600, 8,16 and 24 bpp. I 
haven't tested 1024x768, but i expect it to be the same thing.
I get a working output with CH8398 at 16bit.

I'm fixing the tseng driver (and its wicked use of clockRanges), 
working from et6000 down. But this is taking a lot longer than expected.
I'm currently at modesetting of the et6000. So this will not be a short 
term solution for you.

You might want to use vesa.
