I close this pull request because I understand that this may not be a useful functionality for the regular user of the system, and that there may be other methods of obtaining debug information, by improving initialization messages, etc. I find it especially useful as a debug method (at a personal level of development), so I will make it available in my fork of this project, along with some improvements and optimization that I have made, among others:

Now optional with #define DEBUG in config.inc, and also compatible with Monochrome or 40x24 CGA text modes.
