I'd like to see the "full-speed" patch to ibm-acpi implemented in
any script or in-kernel management scheme I use - I couldn't live
without it.  A patch was posted to this list to provide this, and I
find it invaluable as a short blast of cold air in extreme temperature
situations.

Unsure if it's implemented in any of the above patches or schemes, but I
certainly implemented it in Paul's original script, and it works wonders
for me.
