Jp, I would most definitely be careful in what you chose to do next. The more that you work at trying to remove the screw, the more likely you are to continue to chip away at bits of the head of the screw which would make them easier to remove. Unless you have some precision using a rotary tool, I would not advise it being your first option in cutting into the remaining part of the head of the screws. You might find it more difficult than you had before to get a grip with a driver onto the head. Soldering to the screw could also make for an even messier problem. However, it would probably the safer of the two options you were considering. Unless you are able to solder a strong connection onto the screw heads, you won't find it to be much more use if the solder doesn't provide any more grip or strength in turning the screw to remove it. You said that you are replacing the keyboard anyways. So how important is it to you cost wise and time wise that these screws be removed from the old keyboard? You may find that spending time on this may be more work than its worth.
