lm-sensors not working under 12.1

Tried to check the CPU temps on my laptop today. Sensors had worked fine with 11.4 and KDE 4.84 but now with 12.1 I’m not having much luck. The sensors detected by sensors-detect are the same as before, but…

No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

 This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): y

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): y
Probing for `National Semiconductor LM78' at 0x290...       No

Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): y
Using driver `i2c-i801' for device 0000:00:1f.3: Intel 82801H ICH8

Next adapter: NVIDIA i2c adapter 0 at 1:00.0 (i2c-0)
Do you want to scan it? (YES/no/selectively): y
Adapter cannot be probed, skipping.
Next adapter: NVIDIA i2c adapter 1 at 1:00.0 (i2c-1)
Do you want to scan it? (YES/no/selectively): y
Adapter cannot be probed, skipping.
Next adapter: NVIDIA i2c adapter 2 at 1:00.0 (i2c-2)
Do you want to scan it? (YES/no/selectively): y

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 

Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): y
Copy prog/init/lm_sensors.service to /lib/systemd/system
and run 'systemctl enable lm_sensors.service'
for initialization at boot time.
Unloading i2c-dev... OK
Unloading cpuid... OK

Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

# uname -a
Linux X205.site 3.1.10-1.9-desktop #1 SMP PREEMPT Thu Apr 5 18:48:38 UTC 2012 (4a97ec8) x86_64 x86_64 x86_64 GNU/Linux

/etc/sysconfig/lm_sensors looks OK to me. It contains the following two lines:

HWMON_MODULES=“coretemp”
MODULE_0=coretemp

This Toshiba Laptop now runs 12.2-64 w/ KDE 4.84

This isn’t a critical issue for me, as I’m not having any overheating issues at the moment, but I’d still appreciate your suggestions.

After sensors-detect you have to load the modules yourself, because the
detect script unloads them.
