The datasheets for the SB mention things like clock gating and the ability to disable unused sata and usb ports. I don't know if these would amount to much or if they are handled by the bios, acpi.. whatever already.

I must say that the page you kindly linked, is about an X.Org driver. I even brought the system in recovery mode without any graphical user interface and no graphic acceleration enabled and SB700 chip is still hot. SB700 is a south-bridge chip and in AMD's micro-computer architecture, North-Bridge is used for communication with high speed devices like graphic, ram and sourth-bridge, and south-bridge itself is used to communicate with slower devices like USB ports, SATA, PATA, floppy and etc. So it's not solvable via graphic driver thingy.

The initial post lists temperatures for CPU, GPU, and HDD. I don't see anything about SB there. The only thing that changing the video driver can accomplish is GPU temperature changes.
Also, the fact that the various parts are all tied together in common heat spreaders tends to result in the temperature of one part being dragged up by heat coming off another part.
Go back to the open source driver, set the power profile to low, and see what happens.

After all, is it still necessary to remove proprietary driver from currently installed system, install opensource drivers and enable the low power profile to see whether it helps or not? It takes my time and I guess it won't work.
In the folder of windows drivers of my ACER5536 laptop, there are two folders under graphic driver folder with names:
USBFilter
SB700
After installing SB700 driver in my windows driver, HDD and SB700 chip itself cooled down and I think there must be similar driver which do the trick under Linux. If it's not there (I can't find it on AMD site) I'm ready to write it myself, but don't have any Idea where to start from!
Thanks again. Any other Idea?

Ok. Fresh installed Ubuntu 11.04 AMD64 Alpha 3 with the 64bit kernel 2.6.38-5 on my laptop's hard-drive. Tried to enable the profiles. As in the wiki page of x.org:
You can select the methods via sysfs. Echo "dynpm" or "profile" to /sys/class/drm/card-0/device/power_method.
card0 card0-HDMI-A-1 card0-LVDS-1 card0-VGA-1 controlD64 ttm version
Names in bold are symbolic links. So the address is not applicable without modification. by the way I changed card-0 to card0 and echoed profile and low keywords into related files without double quotations, still no change at all. Also due to lake of proprietary driver from AMD, GPU and CPU are hot too.
If you guys are right and the main reason is the Hard-drive itself, but not SB700 (The temperature of SB700 is much lower when I completely remove the HDD), how can I enable similar power-management features to my hard-drive or it's relating interface (maybe the AHCI)?
