[Bug 462479] [NEW] Fan stops when below 50 C never to start again

Release 9.10

I am on a Fujitsu Siemens Amilo L1310G. If the laptop is cold (below 50
C) when I start it, the fan does not start at all. If it is warm when I
start it, the fan runs until the temperature is below 50 C. The fan then
turns off, never to turn on again (even if the temperatures rise above
50C).

The same issue existed in every version I've tried (I started using
Ubuntu with 8.04), but there was a patch on the laptop testing page
(https://wiki.ubuntu.com/LaptopTestingTeam/FujitsuAmiloL1310G under
"From the start"). This patch made the fan run all the time which was no
problem. This patch does, however, not seem to work with GRUB 2. I can
at least not find a way of getting it to work.

One workaround is to start with acpi=off. Then the fan runs all the
time, but turning ACPI off has, of course some rather unfortunate side
effects.
