After I successfully installed 10.4.8 on a FSC Livebook 7020S I have two major problems:

1) Neither network interface card of the Livebook is recognized (built-in ethernet and WLAN). On the other hand, the internal Firewire adapter is shown as a network adapter.

2) I can not send the machine to sleep (no reaction). Also, when I try to shutdown, it seems to hang while showing a blue screen with the spinning wheel.

Any idea what I could try to get at least one network device working?
