acpi_power_off doesn't turn off HP Pavillion ZE4201

Description of problem:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot up kernel 2.6.8-1.603.
2. Shutdown the system.
The system displays "acpi_power_off", but it doesn't turn off. It
doesn't matter if acpi=on is passed to the kernel - it makes no
The system should switch off. It does with FC2 kernel 2.6.8-1.521.
BTW, for hardware specs, lspci output etc., see bug 122604.
Just for the record, this seems to work fine with 2.6.9-rc4 vanilla
kernel (i.e. the system does get switched off). Hmm...
Strangely enough, the 2.6.8-1.607 kernel, which is based on the above
vanilla rc4, doesn't do this right. Same message: acpi_power_off
called and then nothing. The system stays powered on.
I'm having the same problem. Fujitsu Siemens notebook (celeron 850).
Maybe related to this kernel bug:
Does anyone know if these patches are part of mainline/Fedora kernels?
Maybe they actually do work...
