I see this error message in my syslog on boot due to hald/acpi : Jun 15 19:16:01 localhost hald[2292]: 19:16:01.720 [I] osspec.c:468: Check if the machine is may a laptop ...

Should I configure these options in my kernel ? Reproducible: Always
According to new kernels acpi organisation : CONFIG_ACPI_PROCFS: │ For backwards compatibility, this option allows │ │ deprecated /proc/acpi/ files to exist, even when │ │ they have been replaced by functions in /sys. │ │ The deprecated files (and their replacements) include: │ │ │ /proc/acpi/sleep (/sys/power/state) │ │ /proc/acpi/info (/sys/modules/acpi/parameters/acpica_version) │ │ /proc/acpi/dsdt (/sys/firmware/acpi/tables/DSDT) │ │ /proc/acpi/fadt (/sys/firmware/acpi/tables/FACP) │ │ /proc/acpi/debug_layer (/sys/module/acpi/parameters/debug_layer) │ │ /proc/acpi/debug_level (/sys/module/acpi/parameters/debug_level) │ │ │ │ This option has no effect on /proc/acpi/ files │ │ and functions which do not yet exist in /sys. so in short term the /proc/acpi directory will be removed and hald should see both in /proc/acpi and /sys directories to find drivers to activate.

0.5.11-r7 (and several revisions before it) will now automatically check whether required ACPI /proc options in the kernel have been enabled, which solves the issue that you reported. Sorry that the report initially went unanswered.
