Hm, I've probably botched the watermarks again. Can you please retest with

As this didn't work either, could you point me to a documentation of the
830M so I could have a look myself? Unfortunately, I did not find
anything appropriate, only an overall description of the chipset that
lists all the RAM/addressing related registers and a high-level
description of the gpu features, but nothing detailed on the 2D graphics
and VGA-related registers.
Thanks,
Thomas
