Processor speed limited by _PPC ACPI objects

[ermanno]

I am trying to install openbsd on my laptop, it is quite old and the battery almost dead, I am also using the original 65W PSU, and the bios is setting the _PPC flag to limit the processor speed since the power available might not be enough to run the system at full speed. In practice however problems arises only listening at music at high volume AND putting the CPU in a loop (100%) :-)

On linux I solve the problem setting ignore_ppc=1 for the acpi processor module the lappy works without problems with the loudspeakers muted or at low volume.

I could not find a way to do that on openbsd, possibly at boot time or as soon as possible, otherwise the system is too slow and not usable for me.

Apart that the install worked perfectly and the system works very slowly but very well with openbsd :-)
