Updating the bios has helped me too. My system is a DELL XPS m1330 wich had the same problems described above till I update the bios to A12.
I have to add that there is no need to have any other OS installed to update your bios, just follow the official DELL how-to at http://linux.dell.com/wiki/index.php/Tech/libsmbios_dellBiosUpdate
