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.
