Hi John,
Just on an off chance.. have you tried:
sysctl -a hw.acpi.thermal
and checked for any output?
The following little snippit taken from
the -hackers mailing list awhile back may
also prove informative... It's for a notebook,
but you get the idea.
-John
#define KELVIN_TO_CELSIUS(t) ((t-2732+5)/10)
#include <stdio.h>
int main()
{
int ret;
int intbuf;
size_t len;
ret=sysctlbyname("hw.acpi.thermal.tz0.temperature",&intbuf,&len,NULL,0);
if(ret==0)
printf("tz0 temperarture: %d C\n",KELVIN_TO_CELSIUS(intbuf));
ret=sysctlbyname("hw.acpi.thermal.tz0._CRT",&intbuf,&len,NULL,0);
if(ret==0)
printf("tz0 crit temperarture: %d C\n",KELVIN_TO_CELSIUS(intbuf));
ret=sysctlbyname("hw.acpi.acline",&intbuf,&len,NULL,0);
if(ret==0)
printf("AC Line status: %s\n",intbuf?"online":"offline");
ret=sysctlbyname("hw.acpi.battery.units",&intbuf,&len,NULL,0);
if(ret==0)
printf("Number of battery units: %d\n",intbuf);
ret=sysctlbyname("hw.acpi.battery.state",&intbuf,&len,NULL,0);
if(ret==0)
printf("Battery state: %d\n",intbuf);
ret=sysctlbyname("hw.acpi.battery.life",&intbuf,&len,NULL,0);
if(ret==0)
printf("Remaining battery life: %d%%\n",intbuf);
ret=sysctlbyname("hw.acpi.battery.time",&intbuf,&len,NULL,0);
if(ret==0)
printf("Remaining battery time: %d:%d\n",intbuf/60,intbuf%60);
printf("crit: %d\n",KELVIN_TO_CELSIUS(3732));
return(0);
}

As said by Napolean Bonaparte:
"Never ascribe to malice, that which is adequately explained by incompetence"
After being embraced by MS:
"When accused of malice, always hide behind incompetence".
