Observations with the current version:

1. The font is now a lot smaller.

2. It feels quicker. However, still a bit slow. Something that seems 
very slow is clearing the screen. It's like pulling down a curtain slowly.

3. Booting on the 4k monitor does not work now. Loader looks alright, 
but when it hands over to the kernel, the screen just goes blank, and 
the machine hangs. This worked before.
