guest@amd:~/.gnupg$ cat /proc/acpi/ibm/thermal
temperatures: 59 49 -128 60 38 -128 34 -128 48 50 -128 -128 -128 -128 -128 -128

...sensors are not installed. I see THERMAL EMERGENCY in dmesg, but
I'm not sure how long ago it was generated.

Well, working sensors report temperatures in 34C (battery) to 68C
range (PCI).

guest@amd:~$ cat /proc/acpi/thermal_zone/THM*/*
<setting not supported>
<polling disabled>
state: ok
temperature: 58 C
critical (S5): 127 C
<setting not supported>
<polling disabled>
state: ok
temperature: 67 C
critical (S5): 97 C
passive: 93 C: tc1=5 tc2=4 tsp=600 devices=CPU0 CPU1
guest@amd:~$

Well, being only in kernel log, those messages are not exactly easy to
notice.
