Roman,
using a week old -current (sources as of 2008-12-13), it works at the
syscons console (ctrl+alt+esc). Haven't tested using 1394 or serial.
Interestingly I was at console session #2, pressed ctrl+alt+esc but I
needed to switch to session #1 to actually see the debugger prompt.
Input goes to the debugger even while not seeing it's prompt.
That reminds me of the old debugger problem when using X and
experiencing a kernel panic.
