I see no crash with my GM45 or Radeon HD 5450, or > software rendering.
So the 32768 value seems to come from: /usr/src/sys/dev/pci/drm/i915/i915_reg.h +2301 /* Enable border for unscaled (or aspect-scaled) display */ #define LVDS_BORDER_ENABLE (1 << 15) The whole border thing seems to be dependent on generation (various checks gen < 4 in the code) of the card one has. How would I know that? I can also see there's KMS debug mode that can be turned on. Any clues how to turn that on?

This is better, but still unplayable on this ancient netbook. I've noticed that I can run --window with rice plugin and works mostly as good as the original fullscreen mode. (Workaround) I'll try to get some more puzzle pieces from the sources in meantime, maybe I can come up with something. Thank you, Jan
