I'm seeing similar extreme slowness even on a local machine.

Particularly noticeable is that the monitor displayed on a qemu virtual SDL 
console (i.e. the defaut) slow enough to be practically unusable. It's taking 
the best part of a second to rendering a character.

This is on an otherwise fast machine that does not have accelerated X drivers, 
which suggests we're doing something really dumb like reading from video ram.

I have confirmed that this is caused by r6336.
