The clock might be select with a mechanism that is not in the area
of the standard 16 clocks. This is not supported by XFree86. Another
possibility is that your VMODE (or the handbook) lies about the 72MHz;
also already seen. There is a facility to run an external clock
program (if you manage to find out how the 72MHz clock is enabled),
see the XFree86-1.2 doc on this.

This is a message from kbd_mode (in the startx script). If you use
codrv, just remove kbdmode from the script, for pccons ignore this
message (send to /dev/null).
