Fix for arithmetic evaluation returns error val in bash 4.1.5 on Ubuntu 10.04

2008-01-21T13:47:23Z

edited cleanup() to reset fan level to auto using ecdump (for thinkpads that cannot use `echo level X > $IBM_ACPI/fan`)

2007-07-02T19:04:21Z

added my working hard drive model (no version-increase needed!?)
