    Drip a lot of penetrating oil (Liquid Wrench or similar) on the threads and apply mild heat with a hair dryer. Repeat several times. A large adjustable wrench can be used to span the raised ridge and should allow more torque than the screwdriver you are in the process of ruining.

    Replace the ball bearings when you finally do get it apart.

    This sounds like an old Raleigh proprietary bottom bracket. Usually these will respond to a 16 mm or 5/8" open end wrench.

    It is if you are removing the adjustable cup.

    That's not likely to work, the steel is as hard as a drill bit. Worst case, remove the other side (that's a left hand thread) then use the technique described at: http://sheldonbrown.com/tooltips/bbcups.html

    if you can get the adjustable cup off, leave the other one in, clean it a bit, and feel around with your finger on the fixed cup for pitting. if pitted, follow Sheldon "Unnngggggggghh!!!" Brown's advice. If not pitted, maneuver some grease into there, used caged bearings, and reassemble.
