Power down broken between 2.6.8.1-mm3 and 2.6.8.1-mm4

Power down broken between 2.6.8.1-mm3 and 2.6.8.1-mm4

[Andre Eisenbach]

I reported this problem previously to this list, but finally got around to 
compile about 10 kernels in a row to figure out where the power off got 
broken.

On my Compaq Presario 2100 notebook 'shutdown -h now' does not power off the 
computer anymore since 2.6.8.1-mm4. It works with 2.6.8.1-mm3.

The notebook will perform the regular shutdown until it displays "Power down." 
and then nothing happens.

I've tried to track the code changes, but it seems like everything 
under /drivers/acpi is the same between those two kernels (including 
acpi_power_off)...  So not sure where the problem is.

Let me know if you guys need any additional information or tests.

Thanks,
   Andre
