IIGC the Sager NP8662 basically is a Clevo, the M860ETU (review: http://www.notebookforums.com/thread228495.html
). It's got an Intel PM45 chipset (http://www.intel.com/Products/Notebo...ldocuments.htm
). On a laptop with an equivalent chipset (Dell Latitude E6400 / E6500) http://www.gentoo-wiki.info/Dell_Latitude_E6400_/_E6500
says Bluetooth should be working with hci_usb but you need to switch the bluetooth-device with 'hid2hci'. http://en.gentoo-wiki.com/wiki/Dell_Latitude_E6x00
however says Bluetooth requires hci_usb for kernel < 2.6.27 and btusb for kernel >= 2.6.27 and your dmesg says you're running a 2.6.31 kernel. If checking and changing modules doesn't work for you I suggest you check the http://www.linuxquestions.org/hcl/
(maybe there's something there) and post full specs (hwinfo, lshw, etc) in the hope somebody can add pointers. That's about all the suggestions I have right now...
