At least the 900 and the 901 have connectors for bluetooth; the 901 does have
a bluetooth adaptor soldered to the board, whereas the 900 doesn't have
anything soldered - see "BT_CON" here:
In models (900) where there is nothing attached to BT_CON in the board, the
BIOS *may* try to power up that portion on the board, and *may* return true
even if it's powering up (in vain) an open circuit.
I do not know the algorith used by the acpi driver, nor by the BIOS, to
determine if there is a BT adaptor switched on. *Maybe* the board queries the
hardware on BT_CON and is actually able to tell if there is something
physically attached when powered on, I don't really know about this bit. I
hope it checks for that, but today I've got my pessimist hat on.

I mispelled the command - it's "hcitool dev | grep hci0", with no hyphen.
"hcitool" actually looks for a bluetooth adaptor anywhere in the system. This
method has a drawback: it would return true if I plug a external USB
bluetooth dongle connected to my eeepc.

According to those:
The 904HD model has this four extra keys, but no integrated bluetooth (I'm
guessing an empty BT_CON area in the board just as the 900). I do not know
the behaviour of the 904 about the issue.
The third and fourth keys are meant to be "user-defined", and both have the
icon of an user. Or, at least, what asus believes a user to be: a head and
shoulders similar to the MSN messenger icon.
With the provided Xandros installation, Fn+F2 cycles through both wlan and BT
(see http://img208.imageshack.us/my.php?image=900wbtlv7.jpg ). I prefer
having one of the four extra keys just for toggling BT, though. Feels *much*
more responsive that way.
