The other thing you might want to check out is if you multiboot your 
laptop that any non-FreeBSD operating system may put hardware into an 
inconsistent state. For example, my Acer laptop loses sound if I boot 
Windows then boot FreeBSD. The workaround is either adjust the HDA 
inputs/outputs through sysctl or simply power cycle the laptop.
