The kernel includes the bt3c_cs driver (for the 3Com Bluetooth PC Card). This driver uses /sbin/bluefw to download firmware to the driver. As far as I can tell /sbin/bluefw is not included in any RedHat package. The net result is that the 3Com Bluetooth PC Card doesn't work out of the box. The /sbin/bluefw is included in the bluez-bluefw package on the BlueZ site. I suggest this should be included in Redhat either in the bluez-utils package or in its own package.
