Regarding the delay: I've discovered a weird thing. When the display is garbled, if I insist on outputting more text to the screen, sooner or later it de-garbles! In fact, once the display has been garbled (not easy to do, sometimes I can work for hours in a terminal before it gets garbled, I can't reproduce it always), a continous output makes it de-garble and garble again, in cycles. Looks like an off-by-one error rather than a speed/sync error, am I completely clueless? This happens with vanilla 2.6.19.5, not with the patched one, which I haven't been able to test yet (sorry...).
