Terco, did you ever get your keyboard setup saved?
This will make a sticky change to keyboard layout. I had problems with VASMCC (and even VASM) keyboard layout not sticking.
The Polish programmers keyboard layout is very similar to the US layout so I added the last line below, to the Keyboard section of /etc/X11/xorg.conf
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
Option "XkbLayout" "pl"
You only need that last line.
It works fine now. You will need to put your layout in place of the the "pl". You will find the code when you try to set things in Vasm.
