Linux driver
This card's Bluetooth controller will work with the standard Linux Bluetooth drivers (btusb) with the BlueZ protocol stack. For the built-in softmodem, have a look at the Conexant HSF modem drivers page for more details.
On recent distributions, you can enable/disable the Bluetooth controller with echo 1 > /sys/devices/platform/thinkpad_acpi/bluetooth_enable if you have the thinkpad_acpi kernel module installed. If you don't, use the FnF5 combination instead, as it relies on the embedded controller to work.
Problems
There is an issue regarding connectivity with the built-in softmodem, likely due an outdated K56flex firmware. See Need to disable 56K modem speed for a workaround.
