[...] This probably makes some sense for userland drivers that bind to specific PCI and USB devices, and for any OOT kernel drivers. For applications and userland drivers that depend on specific kernel drivers it would make more sense for the package to specify the kernel driver(s) and for the package manager to look at which drivers have been loaded and bound to devices.
