I cannot prevent "yast2 lan" from loading a blacklisted module:

little:/home/fmf # lsmod|grep acx
little:/home/fmf # yast2 lan
little:/home/fmf # lsmod|grep acx
acx                   145032  0 
firmware_class         14080  1 acx
usbcore               114896  4 acx,ehci_hcd,ohci_hcd,uhci_hcd
little:/home/fmf # less /etc/modprobe.d/blacklist

# Listing a module here prevents modprobe from loading it via modalias (only
# aliases from /lib/modules/*/modules.alias). You may still load it explicitely.
# We blacklist some modules becaus they may harm on certain devices or they
# prevent other modules from grabbing the device.
#
# Syntax:  blacklist <driver name>
# See 'man modprobe'.
#

# too many Tx errors
blacklist acx
