I read about driver problems with intel 3945abg, but is there any progress at work?

I know that many people have this card in their Hacintosh, i just installed Leopard and just hope that solution will be soon.

Not likely. Go to the drivers forum. There's 190+ pages of non working driver + idiots rambling about when it will be done. I can honestly say, it wont be done within a month at least, probably more.
