You can check the temperature by running nvidia-settings. If you can't see the temperature in it, then nvidia doesn't support it on your card and I'm not sure we should :s
Thanks for the vbios you sent me in private. For the others, the reason why he doesn't have temperature anymore is because his vbios lacks sensor calibration values.
In nvidia-settings tab "GPU 0 - (GeForce 6600 GT)" --> "Thermal Settings" is:
Thermal Sensor Information: ID: 0 Target: GPU Provider: GPU Internal Temperature: 70 C (now)
I looked in Windows program SpeedFan. It found Nvidia PCI card and reported "GPU Temp" about 68-70 C. So it looks like both nvidia driver and windows SpeedFan program reading same values.
Great, I'll cook you a patch in a bit and you'll see what the temperature is like. It won't be perfectly accurate but there is some kind of default for nvidia cards of this generation.
Ok, send me patch and I can try it if it will work and report similar values as windows or nvidia driver.
Sorry for the late answer.
Please test this patch. Be aware that temperature with nouveau will be higher than with the blob. I only want to see if nouveau reports a temperature.
The only way to be sure if the values are good-enough would be to use the blob and run: nvapeek 0x15b0 Please send me the result along with the temperature reported by nvidia at the time of the peek.

PS: This patch has only be compile-tested, I don't have access to an nv4x right now.
Hello,
now after patch nouveau report temperature:
$ sensors ... nouveau-pci-0500 Adapter: PCI adapter temp1: +63.0°C (high = +95.0°C, hyst = +3.0°C) (crit = +145.0°C, hyst = +2.0°C) (emerg = +135.0°C, hyst = +5.0°C) ...
I found that nvidia binary driver has command line utility nvidia-smi which report same temperature as X utility nvidia- settings. So I will use nvidia-smi (if it is OK).
And after reboot nvidia report another temperature value:
$ nvidia-smi -q -d TEMPERATURE ... GPU 0000:05:00.0 Temperature Gpu : 70 C
Immediately I called nvapeek command:
$ nvapeek 0x15b0 000015b0: 1000008e
So value reported by nouveau is lower than value reported by nvidia binary driver.
I wait some some and started nvidia-smi and nvapeek again, here are results:
$ nvidia-smi -q -d TEMPERATURE ... GPU 0000:05:00.0 Temperature Gpu : 67 C
$ nvapeek 0x15b0 000015b0: 1000008e
So it looks like that nvapeek returning always same value and does not depends on temperature... It is OK?
