Well, on the Amiga side, the clock is off by approx. 1 hour. Last time I set
it, we still had daylight savings. I was too lazy to adjust for end of
daylight savings. On the linux side, it is off by two hours.

I tried with fbset -fb /dev/fb1 "640x480-60", assuming that afb is loaded as
/dev/fb0 and cirrusfb as /dev/fb1. But the screen did not switch. Either I
mistyped something or it did not work. Testing without seeing something
(error messages, ...) is not really fun.

I tried video=clgen (the one that worked for clgenfb), video=cirrus and
video=cirrusfb. None of them activated the PicassoII board.

It seems to be the right module. The module is able to read the MAC address
of the adapter. Either the module has some other problems or the 2.6 kernel
requires something different in the network configuration? Again, difficult
to test, if there is no display...

The keyboard works fine. Even the right layout (de).
