Did a few more tests:
I tested with 2.6.33 and 2.6.35, and it's not working either, so this does not
seem to be a (recent) regression.

Tried disabling enabled GPE interrupts before shutting down, in
/sys/firmware/acpi/interrupts/, it didn't have any effect.

Finally, I tried disabling wakeup sources in /proc/acpi/wakeup, and I found the
culprit: the "LID" wakeup source.
So running:
echo " LID" > /proc/acpi/wakeup
before shutting down, will have the laptop halt without rebooting whether it's
plugged or not.

I checked in the BIOS, and there's an option "Panel Open - Power On", and it
wasn't enabled. I tried enabling/disabling it, and the problem is reproduced
whether it's on or off.
Also, the problem is reproduced whether the lid is open or closed. And the
problem is fixed with 
echo " LID" > /proc/acpi/wakeup
whether the lid is open or closed.

I don't know yet how to solve this at the kernel level.
