[LOR] ESS Maestro-2E and ACPI power methods

Hi,

I built a -CURRENT kernel dated from this weekend, I simply re-used my
old kernel configuration file without any modification.  There is a LOR
at boot time that I looked for in the known LOR database, but I didn't
find it.  Here is the kernel message without hexadecimal values since I
wrote it manually.  If further debugging informations are needed, just
ask and I would be glad to provide them.
