Hardware support for PowerMac G5 11,2

[N. S. Montanaro]

Hi,

I recently came into possession of a PowerMac G5 quad-core with liquid cooling. Since OS X 10.4 and 10.5 are a bit dated I'm hoping to run FreeBSD instead.

Does 11.1 support the hardware for this particular model? Specifically, I was unsure if the liquid cooling system would need support on the OS level, or if that is handled by OpenFirmware.

Thanks.
