I thought he suggested to put your driver under /sys/dev/acpi_support. I was wrong, he only suggested you should look at for example acpi_toshiba in order to implement some sysctl hooks. Sorry for confusion. > so technically, i suppose i shouldn't discuss it on this list. Well, on the other hand we discuss stuff that don't belong to ACPI, as for example cpufreq..

ACPI still need to go SMM at least for telling the BIOS to switch to ACPI mode (instead of Legacy). It's a transitional phase I believe, but the transition takes a very long time.
