As of this writing (2014-02-18), the latest firmware is 1.3. It can be updated from the webif. Use Safari, the credentials are admin/password. If you're trying to find it on your network, the OUI of the BMC NIC is a0:b3:cc.
apt-get install openipmi ipmitool
SMBIOS incorrectly exports the IO mapped Keyboard Control Style (KCS) interface at address 0xca8 instead of 0xca2. This causes the ipmi_si kernel module to fail to load. Fortunatly we can override the auto-detection with module options. See modinfo ipmi_si for available options. The correct address was found in the IPMI Messaging Interfaces section in the PDF Manual for the N40L

Features are broken out into modules. Unused features can be disabled. ipmi_msghandler, ipmi_devintf, ipmi_si are a bare minimum configuration. Docs are vague regarding the neccessity of ipmi_poweroff for power commands.

The Hetzner IPMI guide is pretty thorough.

I have now a usable second hand remote access card (which admin account was not the default one).
Ipmitool worked ok when using the correct IO address and I finally managed to reset the card to factory defaults :-)
Thanks for the info !
