Installation problem to new pi board (Model B)

[Soundstorm]

I gave it another shot with copying the Hexxeh files to the SD card.

The first time I used the windows installer and chose Xbian Beta 1.1. The copied the files to the SD card.
When powering on the RPi, ACT blinks 1 long time. Screen stays black with a non blinking cursor in the top left corner.

I then gave it another shot with Xbian Beta 1.0 (and copying the files). Same thing happens.

Now, when I use Xbian Alpha 4 (and copying the files), it does some completely different things!
Text starts to roll down like it is doing its job like it's supposed to. It Expands, Reboots, goes black, boots, blinking cursor in top left, and then gives a black screen (no non-blinking cursor either). LNK keeps blinking.
While doing all it's stuff, it does give an error:
could not insert 'snd_bmc2835': exec format error
