+ - Linux & Bluetooth
+
+ With some tweaking bluetooth works as expected.
+ You will need the above mentioned patch patch-2.4.20-mh6 to have full functionality with 2.4.20. Then add
+
+ deb http://bluez.sourceforge.net/download/debian/woody/ ./
+ deb-src http://bluez.sourceforge.net/download/debian/woody/ ./
+
+ to your /etc/apt/sources.list for woody and install at least the packages "bluez-bluefw"
+ for loading the firmware into the usb bluetooth device. You will need "bluez-utils" for hci and rfcomm communications.
+ You need to add this line
+
+ bluefw 0x0003 0x044e 0x3001 0x0000 0x0000 0x00 0x00 0x00 0x00 0x00 0x00 0x00000000
+
+ to your /etc/hotplug/usb/bluefw.usermap to let the bluefw automatically load the appropriate firmware
+ into your dongle once it shows up.
+
+ I am using bluetooth with a Siemens S55, but e.g. Nokia 6310i goeas the same way.
+ For an initial pairing you will need a pin in /etc/bluetooth/pin which at least needs to have 5 digits which is documented near nowhere.
+ Once you do the pairing (Entered pin on the X requester popping up and on the cellphone) you can set your phone to not "Ask on connection".
+ Afterwards i put the rfcomm config into the /etc/bluetooth/rfcomm.conf
+
+ rfcomm0 {
+ device 00:02:EE:B8:50:C5;
+ channel 1;
+ comment "S55 Dialup connection";
+ }
+
+ rfcomm1 {
+ device 00:02:EE:B8:50:C5;
+ channel 9;
+ comment "S55 OBEX";
+ }
+
+ For dialing out via ppp you now can use /dev/rfcomm0 which should lead to your phone asking you to accept the connection.
+ For debugging you can use these commands:
+
+ :~$ sudo hcitool scan
+ Scanning ...

+ - Hardware Notes:
+ x Broadcom 2033 chipset (tested with an ALLNET 7031 Class1 USB Adapter)
+ - Make sure you have bluefw and hotplug installed, then everything works fine right out of the box.
+ x on debian using default or for newer packages above sources:
+ :#apt-get install bluez-bluefw
+ - DO NOT enable the bluetooth.o module to avoid it being loaded by hotplug!!
+ x this can be done by adding 'bluetooth' to '/etc/hotplug/blacklist'
+
+ The Bluetooth device in this laptop is a USB Bluetooth device.
+ By default, Linux provides two different device drivers for USB Bluetooth devices: bluetooth.o and hci_usb.o.
+ The hci_usb.o is the correct driver for this device. Both drivers are loaded when the Bluetooth button is pushed
+ but unfortunately bluetooth.o obtains the device first, not allowing hci_usb.o to use the device.
+ In order for the Bluetooth device to be function, the bluetooth.o driver must not load.
+ One way to stop the bluetooth.o driver from loading is to remove the driver from the system. This is accomplished by doing:
+
+ :#rm /lib/modules/2.4.18-14/kernel/drivers/usb/bluetooth.o
+ :#depmod -a
+
+ Now, if inserting th usb device only the hci_usb.o should be loaded.
+
+ - ACPI
+ x get suspend work
+ - compile kernel with 'Software Suspend Support'
+ - some interesting post:
+ from http://lists.debian.org/debian-laptop/2002/debian-laptop-200208/msg00349.html

+ Last I checked, ACPI does suspend to memory or disk, using swsusp. It's
+ even all integrated into the 2.5 kernels (though the CONFIG_SWSUSP option is
