That looks fine.  I assume fs_size is the size of the ramdisk for the /
partition.  I think it is in kilobytes.

You only need to use beofdisk if you need to partition hard drives on the
slaves.  Boot-disks should be fine.

I don't know what is wrong with your card.  Are you able to configure the
card on your master?  On the master you probably want to use eth0 to go to
the outside world, and have eth1 be for the beowulf slaves.  You can
change that in /etc/beowulf/config
