Hi,

2.) I let xdm manage the local server running Xcfbpmax. It seems that 
    when entering username and password, only the left shift key of my 
    LK401 keyboard is working properly, not the right one. I guess this 
    can be cured with suitable xmodmap commands, but translations in the
    resource file might be more convenient. Does anybody happen to know 
    whether there is a way?

This occurs because the LK201 generates "left shift" for both shift keys
and since the "real pmax" uses an LK201... (Sorry, but I don't know the
easy way to fix it.)
