That changes everything - I thought you were talking about Linux _console_
applications on L4Linux's _console_ :-)

Yes, that's annoying. I always use a combination of "xset m 0 0" and
moving the cursor into the upper left corner. We have no better solution
so far. An L4Linux and X driver for absolute coordinates would solve this
issue but is not as easily available as the current one.

Be free to modify dope at will. I suggest to begin with
dope/server/common/vscreen.c.
