- catch up with the changes to the interrupt functions - change the way we handle the list of handlers to use a standard function rather than a home spun one :) - don't add every function on a pci device as a seperate device - add more info to the pci_info structure - when FULL_MONTY turned on show more information git-svn-id: file:///srv/svn/repos/haiku/trunk/current@340 a95241bf-73f2-0310-859d-f6bbb57e9c96
