When I bought my mobile, my provider offered a bluetooth headset for free in addition.
This is what i did to get it running with Fedora Core 3
First have a look at http://www.gargan.org/linux/snd-bt-sco/

Install the following necessary packages:

automake
autoconf
alsa-lib-devel
bluez-libs-devel
libao-devel
alsa-tools


Checkout the cvs-repository:

cvs -d:pserver:anonymous@cvs.sf.net:/cvsroot/bluetooth-alsa login
cvs -d:pserver:anonymous@cvs.sf.net:/cvsroot/bluetooth-alsa co btsco


Then build the userland-daemon:

cd btsco/
./bootstrap
./configure
make
make install


Finally build the kernel module:

cd kernel
make
make install
depmod


Now install the kernel module:

modprobe snd-bt-sco


For testing I used xmms. Just run the daemon

btsco <bdaddr>

Start xmms, select the Alsa Output Plugin, click on configure and select your headset as Output Device. Now play your favourite music and enjoy it.
