I debugged further with a recent OpenBSD 4.1 snapshot and can
claim the following:

- plain Xorg vesa drivers don't support widescreen formats
  (16:9 and 16:10 formats are discussed to be supported _maybe_
  in future VESA specs - so people who claim that
  Xorg's vesa driver works with a 1920x1200 resolution simply
  can't read the output of xdpyinfo or Xorg.N.log)

- FireGL 5200 is a rv530 (x1600) chip derivative. Those chips
  are not supported by the ati/radeon Xorg drivers - and ATI
  doesn't provide any documentation. So owners of such cards
  have no luck if they can't use fglrx

- I also tried to get fglrx working using the bits some FreeBSE
  people already hacked together (namely frglx-freebsd.com),
  without success (and really if things need linux emulation
  layer I can simply install linux and good is). Not to mention
  that frglx-freebsd totally sucks and is a very suckish hack...

So I have to stay with Linux because I can't sell and buy
another computer (it is simply the notebook of my work). ;(((

Regards,
Anselm
