Hi,
I remember having intermittent fan problems on a HP after some suspend/resume
cycles. Browsing acpi-devel, i found the following post from Matthew Garrett:
http://article.gmane.org/gmane.linux.acpi.devel/16643
I'd suggest we also do the following:

This should never do any harm (famous last words 8*)
