Setting the sysctl doesn't work:

Oct 22 09:50:15 NB0117232 sudo:   engels : TTY=pts/3 ;  
PWD=/usr/home/engels ; USER=root ; COMMAND=/sbin/sysctl  
hw.acpi.thermal.user_override=1
Oct 22 09:50:45 NB0117232 kernel: acpi_tz1: _CRT value is absurd,  
ignored (256.0C)
Oct 22 09:50:55 NB0117232 sudo:   engels : TTY=pts/3 ;  
PWD=/usr/home/engels ; USER=root ; COMMAND=/sbin/sysctl  
hw.acpi.thermal.tz1._CRT=105C
Oct 22 09:51:03 NB0117232 kernel: acpi_tz1: _CRT value is absurd,  
ignored (256.0C)

hw.acpi.thermal.tz1._CRT: -1

It is only set to the overridden value for a moment and is then set  
back to -1.

So a workaround in the code would be nice.
