+  Similar to acpi_enforce_resources=lax, but only affects this driver.
+  ACPI resource conflicts are ignored if this parameter is provided and
+  set to 1.
+  Provided since there are reports that system-wide acpi_enfore_resources=lax
+  can result in boot failures on some systems.
+  Note: This is inherently risky since it means that both ACPI and this driver

+  worst case, result in unexpected system reboots.

+
+  If set to 1, the driver uses MMIO to access the chip if supported. This is
+  faster and less risky (untested!).

 This information _might_ give us enough information to add experimental support
 for the chip in question. No guarantees, though - unless a datasheet is
 available, something is likely to be wrong.

+There is a persistent perception that changes in this driver would have impact
