Writing 15361 (i.e. 0x3C01) to ACPI_REGISTER_PM1A_CONTROL appears to
hang my system in acpi_os_write_port(). What can I do about that?
Another observation: if I connect a screen to the system's VGA port,
when I call 'poweroff' the screen goes into power saving mode. This
seems to indicate that the integrated video card is properly shut down.
So the fans keep spinning, the LEDs keep shining, the LCD keeps
displaying, but the video card is shut down?
Might this help pinpoint the problem?
Check the BIOS to see if the "Power Button" is configured to
shut the system down. Some BIOS configure APM to do what
the power button does!
Here is the relevant BIOS menu.

'Instant-Off' is the appropriate setting, right?
In a different menu, there are two other (relevant?) options:
PWRON After PWR-Fail [On]
Watch Dog Timer Select [Disabled]
