My configuration manager was written with this sort of thing in mind (though I
was thinking in terms of PnP-BIOS hot-swap at the time)... It uses automatic
rebinding of resources (with driver notification) as its method of conflict

However, I haven't gone through and modified the majority of the vast
collection of drivers that Linux has available, as (1) I can't test most of
them, and (2) I would have to re-modify them every time I ported to a new
kernel version.
