Just found another ACPI bug in 2.6: > config ACPI_HT > bool "ACPI Processor Enumeration for HT" > depends on (X86 && X86_LOCAL_APIC) > default y [...] > config ACPI > bool "Full ACPI Support" > depends on !X86_VISWS > depends on !IA64_HP_SIM > depends on IA64 || (X86 && ACPI_HT) So CONFIG_ACPI is not allowed on uniprocessor anymore, _and_ it requires HyperThreading code? ;-) No wonder CONFIG_ACPI didn't appear for my uniprocessor Pentium3 'make oldconfig' ;-) (ACPI requires ACPI_HT, which requires LOCAL_APIC) Another reason why I was saying that CONFIG_ACPI should be the toplevel config option (even if CONFIG_ACPI never actually appears in any code, but only in Kconfig)...
