wireless.
After vasting a lot of time and growing a few more grey hairs I finally had the grand idea to copy from VL-7-Live the following files
to Salix: /lib/firmware/b43 and ../b43legacy as well as all the files /lib/firmware/bcm43xx*.
Having done this and enable wlan0 in /etc/rc.d/rc.inet1.conf the wireless Interconnection roared to live.

Question: why are those files not included in Salix when apparently they are needed for wirless Internet connection at least in this small lappy?
