Hi Steinar, I've had a little experience using the Hobby Boards new humidity sensor. While I haven't been able to test the sensor in high humidity conditions (I've only been using it inside), the temperature reading is does produce seems a little different from a DS1820. In my case however, the humidity sensor is reading less than the DS1820 (it varies between 0.5 to 1 degC).
I also cannot update the polling frequency through owfs by writing to the the polling_frequency file. I think it should work, but suspect there is a bug in the owfs software. The only way I have successfully updated the polling frequency is by using the HBviewer software available on the Hobby Boards web site: http://www.hobby-boards.com/store/pages.php?pageid=14 However, It only runs on Windows and you'll also need to install a 1-wire driver, which is also available from the Hobby Boards web site. Hope this helps.
