NM uses udev to find devices.
However here NM can't recognize devices, they don't probably set up sysfs 
correctly.

What drivers and kernel version do you use?
Can you run:
$ lspci -nn | grep Network
$ lspci -nn | grep Ethernet

I see in the logs:
  Linux version 2.6.26-2-686 (Debian 2.6.26-27) (dannf debian org) (gcc  
version 4.1.3 20080704 (prerelease) (Debian 4.1.2-25)) #1 SMP Wed Sep 21 
04:35:47 UTC 2011
  sky2 driver for eth0
  NDIS for wlan0
  (wlan0: ethernet device 00:23:4e:36:29:0a using NDIS driver: bcmwl5,  
version: 0x4aa190c, NDIS version: 0x501, vendor: 'NDIS Network Adapter', 
14E4:4315.5.conf)

I suggest you upgraded to a final release.

Links for drivers:
http://wiki.debian.org/sky2
http://wiki.debian.org/bcm43xx

Also, would you provide output for commands in these links:
