Try this (which will make no difference to the effectiveness of APM on this
machine):
> CONFIG_PM=y
>
> CONFIG_APM=y
> CONFIG_APM_DO_ENABLE=n
> CONFIG_APM_CPU_IDLE=n
> CONFIG_APM_DISPLAY_BLANK=y
> CONFIG_APM_REAL_MODE_POWER_OFF=y
>
> CONFIG_CPU_FREQ=n
> CONFIG_CPU_FREQ_TABLE=n
>
> CONFIG_X86_SPEEDSTEP=n
Reasoning:
cpufreq and speedstep don't work on Dell P3 laptops anyway, and the
*internal power supplies* of the i8x00 series make wierd noises when APM
tries to idle the CPU. The board will do this anyway, without making
noise, so linux need not.
