Any clues as to what VESA is doing? Not the slightest idea. I don't understand what your code is doing either, I only bisected it in order to get a running linux-next kernel. > And what is the nature of the regression? The machine is very much alive, but the screen output is garbled. On the text console, it shows a couple of characters around the cursor position all over the screen. In X, it seems to be similar. The kdm login screen gets shown as a nice pattern of colours, and they change when I move the mouse. I can't identify anything visible on the screen though. Trying with i915 KMS next.
