After a reflash with the latest alpha2 the card works (at 230400 for the moment).
From hciattach.c
00830 /* Socket Bluetooth CF Card (Rev G) */
00831 { "socket", 0x0104, 0x0096, HCI_UART_BCSP, 230400, 230400, 0, bcsp },
Just edited /etc/sysconfig/bluetooth
BLUETOOTH=yes
BLUETOOTH_PORT=/dev/ttyS3
BLUETOOTH_PROTOCOL=bcsp
BLUETOOTH_SPEED=230400
et voilà ...
The speed should come up to 921600, but I have before to check the speed of the serial port.
(setserial /dev/ttyS3 baud_base 921600 would be optimal but I have to try)

P.S.
I don't see the dbus_pin_helper mentioned in /etc/bluetooth/hcid.conf, so I tried installing bluez-dbus-bluepin but don't see any difference, the phone disconnects after "spdtool browse". I think it is just a "pairing" issue. The last option would be the "old but good" givepin script.
