Slackware and PAL2.0

Hi,
  Is there any of you here using Slackware? And if yes, were you able
to connect to PAL2.0 with it? I've been struggling with it for a week,
trying all kind of instruction, and still fail to do that. I have
tried Shuey's instruction as well as the one about Wicd I found here.
It seems to me that the moment they try to do with the certificate,
something went wrong. Can any of you help me on this?

Thanks a lot.
