* console/inch.c, console/keyboard.c, console/pc_keyb.c,
console/vt.c, include/bsp.h: Correct incorrect interrupt level
handling in new keyboard management code. Correct
BSP_poll_char initialization routine.
* start/start.S, startup/bspstart.c: Correct when the video is
initialized.
* timer/timer.c (Calibrate_1ms_loop): Address problem where this
did not work correctly on all PC speeds. The new calibrate routine
has been tested on Pentium 166, pentium II 200, pentium III
300 Mhz and does work as expected.
