Help with AR242x 802.11abg Wireless PCI Express Adapter (rev 01)

[A R C]

Hi team, I have a Toshiba Satellite A205 S5831, running sid, and I
have not been able to make the wireless work. I have found references
in several places, pointing to madwifi, ndiswrapper, etc. I have
installed all these packages, but no success so far. I wonder if there
is a howto somewhere, or anything that you could point me to that
would help me fix this issue. Since I am running sid, some solution
independent of kernel image update would be the best, however, I am
willing to try anything (I believe that ndiswrapper requires tweaking
the kernel, if so I have not done it=.
Thanks,
AR
