        sys/arch/x86/pci/ichlpcib.c: revision 1.51
Disable gpio(4) attachment to ichlpcib(4) by default.
The GPIO lines on an ICH are usually connected to opaque platform-
defined functionality, and may be manipulated by the ACPI DSDT or other
mechanisms behind our backs.  In one instance, it was found this
in combiation with gpio_resume() sabotaged repeated suspend/resume cycles.
GPIO functionality can be enabled by setting ichlpcib_gpio_disable to 0,
for instance with `gdb -write`.
