I have a very similar problem with 8.10 on my Dell Inspiront 640m (equivalent to the E1504)

I have the same problems as Karl M except I do not have anything using large amounts of CPU when the keyboard is non responsive.

One other strange behavior I noticed is that when the gnome-power-manager is on there does not appear to be a one to one correlation between pressing fn-up/down and brightness level changes. However the brightness changes just fine(aka one step per press) with the gnome-power-manager off).
