When booting 2.6.31-rc6 on some x86-64 hardware with fan control and
monitoring via the Winbond 83627 chip, 2.6.31-rc6 prevents the module
using an I/O region [1] described in the ACPI DSDT table [2] - which
didn't occur in -rc5.
Is there a way to relax this, or does it require adding
acpi_bus_register_driver(struct acpi_driver) and the needed code this
late in the game?
Thanks,
Daniel

This is only a warning, it doesn't prevent reserving the region by
default, does it?
