Will get you the log files later (currently not at the right location)

Regarding the iBFT capable network card: I am not using any special 
network card either, but am creating the iBFT in software by booting 
iPXE ( http://www.ipxe.org/ ) first, and creating the iBFT using a 
script along the lines of:

==
#!ipxe
set initiator-iqn initiator-iqn
set username my-username
set password my-password
set keep-san 1
set skip-san-boot 1
sanboot iscsi:1.2.3.4::3260::my-target-iqn
kernel http://webserver-containing-opensuse/boot/x86_64/loader/linux 
textmode=1 install=http://webserver-containing-opensuse 
autoyast=https://my-webserver/autoyast-generating-script.php
initrd http://webserver-containing-opensuse/boot/x86_64/loader/initrd
boot
==

That works for other OSes, which search for the iBFT table left at a 
known memory region by iPXE and use the information.
(they either call "iscsistart -b" which uses the information to connect 
automatically, or they modprobe iscsi_ibft, and query the information 
through /sys)
