Undocumented configuration symbols in 2.4.6pre2
The 2.4.6-pre2 kernel introduces some new configuration symbols:
CONFIG_AMD7409_OVERRIDECONFIG_BLK_DEV_AMD7409CONFIG_BLK_DEV_OSB4CONFIG_BLUEZCONFIG_BLUEZ_HCIEMUCONFIG_BLUEZ_HCIUARTCONFIG_BLUEZ_HCIUSBCONFIG_BLUEZ_L2CAP
Would the people responsible for these symbols please write Configure.help entries and send them to me? Before this update Configure.help had complete coverage; let's try to keep it that way.

Yep, those are mine. They belong to Linux Bluetooth subsystem.
btw Linux is the first OS that has official Bluetooth support.
Here we go:
CONFIG_BLUEZ
Bluetooth is low-cost, low-power, short-range wireless technology. It was designed as a replacement for cables and other short-range technologies like IrDA. Bluetooth operates in personal area range that typically extends up to 10 meters.
More information about Bluetooth can be found at http://www.bluetooth.com
Linux Bluetooth subsystem consist of several layers:
HCI Core (device and connection manager, scheduler) HCI Device drivers (interface to the hardware) L2CAP Module (L2CAP protocol)
Say Y here to enable Linux Bluetooth support and to build HCI Core layer.
To use Linux Bluetooth subsystem, you will need several user-space utilities like hciconfig and hcid. These utilities and updates to Bluetooth kernel modules are provided in the BlueZ package.
For more information, see http://bluez.sf.net.
If you want to compile HCI Core as module (hci.o) say M here.
Not unsure ? say N.
CONFIG_BLUEZ_L2CAP
L2CAP (Logical Link Control and Adaptation Protocol) provides connection oriented and connection-less data transport. L2CAP support is required for most Bluetooth applications.
Say Y here to compile L2CAP support into the kernel or say M to compile it as module (l2cap.o).
Not unsure ? say M.
CONFIG_BLUEZ_HCIUART
Bluetooth HCI UART driver.
This driver is required if you want to use Bluetooth devices with serial port interface.
Say Y here to compile support for Bluetooth UART devices into the kernel or say M to compile it as module (hci_uart.o).
Not unsure ? say M.
CONFIG_BLUEZ_HCIUSB
Bluetooth HCI USB driver.
This driver is required if you want to use Bluetooth devices with USB interface.
Say Y here to compile support for Bluetooth USB devices into the kernel or say M to compile it as module (hci_usb.o).
Not unsure ? say M.
CONFIG_BLUEZ_HCIEMU
Bluetooth Virtual HCI device driver.
This driver is required if you want to use HCI Emulation software.
Say Y here to compile support for Virtual HCI devices into the kernel or say M to compile it as module (hci_usb.o).
Not unsure ? say M.
Thanks
