Please, use the /NOSUPERIO command line switch.
If you would like, I might add some debug code to try to completely track down this issue.

Ok, using the /NOSUPERIO switch works in so much that Speedfan starts up correctly.

No voltage/fan readings are present (only hdd temp), though, but I guess this is expected after using the /NOSUPERIO switch.

If you want to send me a debug version, I will be glad to try it - thanks.

Update: After checking the "DELL support" checkbox and can read fan speeds and CPU temperature (no voltages). I will try to get fan speed control to work.
