Improve text layer in LE2

Browse Source 
- set display enable to be ON by default.  LE2 doesn't turn it on until after the test screens, which would seem to indicate that the register should default to on, otherwise they're always invisible.
  - added a kludge to use the right palette for the text layer in LE2, I haven't checked, but I wonder if this could also be related to internal defaults for the mixer chip which the game doesn't change.

This allows you to see the ram/rom tests anyway, which is better than an invisible startup.
