If you go to Device Manager, and check the properties of "Computer",
does it say "Standard PC" or "ACPI Multiprocesssor PC" ? If the HAL
is "Standard PC", that would explain the limited options to turn off
the computer.
If you did a clean install, did you get an error message, about some
problem with ACPI ? Like "not compliant" ? I had that happen with one
Asus BIOS, where when I tried to install, the ACPI tables from the BIOS,
were not to the OS installer's liking. I ended up with a "Standard PC"
as a result, and had to endure that "it is safe to turn off your PC"
crap.
Once I tried a later version of the BIOS, then I could install an
ACPI HAL, as normal.
Some HAL changes are easy. Changing from one flavor of ACPI HAL
to another, is a "driver change". But I suspect that escaping from
"Standard PC" is not going to be so easy.

During an OS install, you can press F5 to force a HAL. Normally
I think it would select an ACPI HAL without any coaching, if
the ingredients are there.

Also, when using Ubuntu, did you examine the log messages that
occur during boot ? Were there any complaints about the ACPI tables
passed by the BIOS ? You might get more useful info from Linux, than
from Windows, if there is a problem.
There are also a couple of reports here, of weirdness with that
motherboard. One guy could not get both cores to be recognized
when using a dual core processor. (Make sure you report your problem
to Asus tech support, so maybe in three months time, you'll see
a new BIOS release with a fix. Asus is probably not monitoring
these forums, looking for trouble.)
