Not sure where the ssb comes from as alternative but could be a firmware one and if it is it should show someting in lsmod.
Vista = shredded my 5 coppies just a few days after I tried it several months ago as no one wanted to take it even with money being overed to take it and a keg of real good beer.
The windows drivers I used was from xp pro sp2 or compatible with this and worked for me iin pre PE versions / other linux distro's.
I have the dell 1390 / bcm4311mcg now as I type this but have not yet downloaded PE = internet here is slow waiting for decent something to be installed .
Try these ones that worked for me for bcm4311mcg / Dell 1390 , you will need all of them likely and from xp pro sp2 32bit so should work instead of Vista ones.http://distro.ibiblio.org/pub/linux/dis ... cm4311mcg/
Also first uninstall the other drivers from ndiswrapper just in case after downloading the linked ones then install linked ones.
Will try to upload some other ones.
For the bcm4312 no idea what works for it but default ones in link might / generic ones from Dell.
Hope this works for you.
