configure-x.sh generates broken xorg.conf files from lts.conf

Binary package hint: ltsp-client-core

Many of the options available in /var/lib/tftpboot/ltsp/i386/lts.conf
don't work properly.

There are five different bugs here; forgive me for lumping them
all together, but they all come to down to "configure-x.sh is
pretty broken".

1: When I specify

        XKBOPTIONS = "ctrl:nocaps"

it is ignored, because it is overridden by
/opt/ltsp/i386/etc/default/console-setup.
The priority of those should go the other way.

2: When I specify

        X_MOUSE_DEVICE = "/dev/gpmdata"
        X_MOUSE_PROTOCOL = "MouseSystems"

I get a "Mouse1" that does that, but "Mouse0" is still using
/dev/input/mice! The reason that I'm using gpm is so that I
can re-map the mouse buttons, and this doesn't help at all.
When I specify X_MOUSE_DEVICE, it must *override* the default
mouse, not turn into an *additional* mouse.

3: Furthermore, it creates an xorg.conf file with a syntax error.
It writes:

 Option Device /dev/gpmdata

but that causes an error unless those strings are quoted, like:

 Option "Device" "/dev/gpmdata"

4: There is no way to turn off DPMS. I need a way to add the line

 Option "DPMS" "off"

5: There is no way to specify that the DRI module must not be loaded.
I need a way to *delete* the line

 Load "dri"
