howto debug acpi_thermal on Dell 2500 servers

Hi,
   I am trying to figure out how to use ACPI to get thermal info on
Dell 2500 servers.  I have compiled acpi into the kernel  (see below
for problems with acpi as module with ACPI_DEBUG in make.conf).  I
can't seem to get any addtional info from acpi.   Do I need a debug
kernel?  Do I have to have more options in my kernel config?  Is
someone already doing (done?) this and I shouldn't bother to try and
debug it?

Thanks, Ken
I tried to include any relevant details that I saw in other messages
in the archives:

I seemed to get more info without ACPI_DEBUG on and the acpi as a KLD.
sidenote: kernel would not load the acpi.ko file if I made it with
ACPI_DEBUG=1 in make.conf. (See way below)

now I am using:
device          acpi
options         ACPI_DEBUG

I tried adding OPTIONS ACPI_VERBOSE but it gives 'unknown option
"ACPI_VERBOSE" '

  My loader.conf is as follows:
riker# cat /boot/loader.conf
hw.acpi.debug=1
hw.acpi.verbose = 1
debug.acpi.layer = "ACPI_ALL_COMPONENTS ACPI_FAN ACPI_THERMAL"
debug.acpi.level = "ACPI_LV_WARN ACPI_LV_ERROR ACPI_LV_OBJECTS"
