Len, Please consider applying the following 4 patches. 2 of them are very somple and fix oopses (the one involving backlight can be triggered on any alptop that does not export backlight controls in DSDT, the other one can only be triggered if cooling device registration fails) and I think should be merged in 2.6.31. The other 2 more of a cleanups (although the 4th one fixes another potential oops at unloading) and can wait till later.
