Andy, Safe to say it was a mistake for me to have "CONFIG_ACPI_HT be a pre-requisite for CONFIG_ACPI". Too many people were confused when they ran config; and those without HT were downright preplexed... Going going back to the CONFIG_ACPI controls all ACPI scheme.... In the 2.4.22 case, CONFIG_ACPI_HT_ONLY pulls in acpitables.o, which are completely self-contained. As CONFIG_ACPI is defined for the HT_ONLY case, CONFIG_ACPI_BOOT is used to enable building drivers/acpi/ In the 2.4.23/2.6 movie, the options are the same, but acpitables.o is gone. CONFIG_ACPI_BOOT is always set, no matter if HT_ONLY or not. The rough edge here is that stuff like sony and ipmi use CONFIG_ACPI at build time, not realizing that HT_ONLY is set until run-time when the discover acpi_disabled. They'd still have to check acpi_disabled if they used something like CONFIG_ACPI_INTERPRETER to indicate run-time support because it may not load; but at least if it _wasn't_ defined, they'd know at build time not to assume ACPI.
