It looks like I do and I can:
jaunty2 at laptop:~$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:       +44.5°C  (crit = +126.0°C)

Furthermore:
jaunty2 at laptop:~$ cat /proc/acpi/battery/BAT0/info
present:                 yes
design capacity:         4400 mAh
last full capacity:      4400 mAh
battery technology:      rechargeable
design voltage:          10800 mV
design capacity warning: 440 mAh
design capacity low:     133 mAh
capacity granularity 1:  44 mAh
capacity granularity 2:  44 mAh
model number:             DELL00
serial number:           27
battery type:            LION
OEM info:                MSL
jaunty2 at laptop:~$ cat /proc/acpi/battery/BAT0/state
present:                 yes
capacity state:          ok
charging state:          charging
present rate:            1 mA
remaining capacity:      1547 mAh
present voltage:         12433 mV
jaunty2 at laptop:~$ cat /proc/acpi/battery/BAT0/alarm
alarm:                   440 mAh
jaunty2 at laptop:~$


Therefore it looks like all the relevant info is available, in standard places.

Is that what is now called System Monitor? That is what I get when I
run the command ksysguard in Konsole (KDE 4.3). It does not have an
"Advanced Power Management" tab or option, and I cannot find a Sensor
Tree nor Battery Charge anywhere. I suspect that these have not been
ported over from KDE 3.x.
