Rene Herman recently removed the only in-tree driver uses of: pnp_init_resource_table() pnp_manual_config_dev() pnp_resource_change() in this change: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=109c53f840e551d6e99ecfd8b0131a968332c89f These are no longer used in the PNP core either, so we can just remove them completely. It's possible that there are out-of-tree drivers that use these interfaces. They should be changed to either (1) use PNP quirks to work around broken hardware or firmware, or (2) use the sysfs interfaces to control resource usage from userspace.
