Problem discovered with monitor power-off with bios
hyperthreading enabled. If hyperthreading is enabled,
the monitor does not shut down at the defined time.
Screen saver functions as expected, but the monitor stays
powered on. If the time setting on the shut-down delay
is altered and applied then the monitor does shut down as
expected after the time delay. Incorrect behaviour
reappears after a reboot.

The monitor power-off functions as expected if
hyperthreading is disabled in the BIOS.

This problem has been encountered on an AOpen MX46-533V
motherboard, at rev 1.07 BOIS. The CPU is a P4 3.06GHZ
Intel chip.
