My laptop has a Pentium III 600 (Coppermine) CPU, and none of the various CPU frequency/scaling kernel modules are loadable. This means that the subdirectories under /sys for controlling throttling etc are non-existent.

With ACPI enabled, the kernel seems to run slowly right from the start. When I use 'acpi=off' the system boots at normal speed.
