in /sys/devices/system/cpu/cpu0/cpufreq are a lot of goodies:

cpuinfo_cur_freq
cpuinfo_max_freq
cpuinfo_min_freq
scaling_available_frequencies
scaling_available_governors
scaling_cur_freq
scaling_driver
scaling_governor
scaling_max_freq
scaling_min_freq
scaling_setspeed

so we might add at least:
system.processor.minimum_speed
system.processor.current_speed

if not more appropriate:

system.processor.available_speeds (instead of min and max)

because on Pentium M we have multiple frequencies: 
cat scaling_available_frequencies 
1700000 1400000 1200000 1000000 800000 600000

Well, I think we have to add another battery key:
battery.present BOOL
because we may have an acpi entry for 2 batteries, but only one currently
present.
At least I have it this way, and I know some others have this too:
 find /proc/acpi/battery/
/proc/acpi/battery/
/proc/acpi/battery/BAT1
/proc/acpi/battery/BAT1/alarm
/proc/acpi/battery/BAT1/state
/proc/acpi/battery/BAT1/info
/proc/acpi/battery/BAT0
/proc/acpi/battery/BAT0/alarm
/proc/acpi/battery/BAT0/state
/proc/acpi/battery/BAT0/info

[root at t41 root]# cat /proc/acpi/battery/BAT1/info
present:                 no
[root at t41 root]# cat /proc/acpi/battery/BAT0/info
present:                 yes

Yeah, I was just starting to sleep at the crack of dawn.. :)
