Jean Delvare submitted a patch which may allow you to use the GPIO pins
in banks not claimed by the BIOS:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=4f600ada70beeb1dfe08e11e871bf31015aa0a3d

This patch is not in 3.6, but will be included in 3.7.

You could also try adding "acpi_enforce_resources=lax" or
"acpi_enforce_resources=no" to your kernel parameters to disable the
ACPI conflict checking.  Note this could have other unintended
consequences.

Best,
Peter
