Yes, currently, the value of 500 lines is hard-coded. The buffer size is
calculated like this:
    (500 lines) x (screen width in characters with the current font)

When you load a GPU driver (*kms), the resolution allows more characters
on a line on the screen, therefore the buffer gets larger.

The size of the buffer could be a runtime setting (a sysctl?), the code
permits this. It just needs to be done™ :)
