I have a HP DL560, currently running Debian Squeeze as dom0 on Xen Hypervisor, and the fans constantly run at 100%. In the past this wasn't a problem because I could install HP's ASM which includes fan management. However since I have installed a xen enabled kernel, the hp-health driver (the piece of ASM that controls the fans) won't start (at boot or manually). Anyone know of any way to make it work? (Or any other method of controlling the fans safely.)

Note that the server has four i386 Xeon CPUs, each with its own fan, plus an extra case fan, and all of the fans can be doubled for redundancy. Also everything works fine under Squeeze without the xen-enabled kernel (can still boot the other one and hp-health loads fine on boot).
