I've heard dust and dirt inside the MB/MBP can cause the trackpad to act very weird. I'm having issues with my mouse now and am thinking of taking apart my MBP and blowing it out with a compressor.

How to fix a Macbook Pro trackpad where the mouse pointer is randomly moving?
I try to compile Raspbian, [ http://hermess.no-ip.org/rpi/index.php ]
when I Prime kernel with the old config: make ARCH=arm CROSS_COMPILE=${CCPREFIX} oldconfig I get a lot lot of dialog messages, so is the file .config useless???
