kernel-2.6.18-1.2200.fc5 - cooling fan powers off at boot time.

[Oliver Leitner]

I have the same problem with my acer laptop, it seems that the acpi support
in 2.6 kernel is at the moment a bit buggy, if a programmer reads this list,
it would be greatly appreciated, that this got fixed, laptops under linux
are at least 10 degrees of celsius above a windows installation...

ive had this problem not only with my own acer, but with other laptops
too... not all though, so i think its a problem with the definitions of acpi
devices...

i have an acer tm 250 btw.
