The LPP is very cool, and we use it extensively here. If you don't want to
see the progress however, I suggest that you don't apply the whole progress
patch, and just replace the boot image (there are great instructions within
the LPP, as well as a couple of apps to help you do it).
However, big note: If you do use the LPP, then you will probably redirect
your console to /dev/tty2 (which redirects the kernel messages to another
console). If you do so, Microwindows tty and ttyscan drivers will *NOT* work
like you expect (since they are linked to the console). In many cases they
do not work at all. Apply the following patch to kbd_tty.c (make the same
changes to kbd_ttyscan.c if you want), and set the the envionment variable
CONSOLE to which ever tty you are running your Nano-X server on.
Clear as mud??
