The timer works perfectly! While looking for timer anomalies I
figured out what really happens: It's our vidconsole.c's iskey which
gets its return code reversed.
The result is that the boot code's autoboot function asks the BIOS for
a keypress. There is none, yet despite iskey's claim to the contra-
ry. *boom* It hangs until the user presses a key and can't update the
time count. And of course it never can time out for the same reason.
This will make it work:
