The basic architecture is pretty straightforward if you think about it: Device drivers should to the extent sensible and possible be independent of the attachement of the device (pccard/isa-card/pci/integrated function) Device drivers should probe and attach after the system is "up" rather than before interrupts and timers and stuff work. Device drivers must be able to handle, as sensible as possible that devices go away (with or without warning). I will happily help you guys hash out these things, but I would far prefer that you guys take a bite out of it yourself first, that way credit goes where credit belongs. First though, do a bit of background study: Suggest you start by examining the "new bus" stuff which is happening on the side (ask Garrett, Dough and that gang) Figure out how a docking station works (PnP) Find the basics of PCCard and CardBus and hot-plug PCI. All the while, think about how this "should Do The Right Thing" on a UNIX machine... We can get Jonathan to create us a mail-list for this once we gain momentum.
