Ok, here are the observations with b43 driver b43 loads and sees access points. But the number of access points seen with b43 are much less than ndiswrapper.
ex: with ndiswrapper, i can see 10 APs but with b43 I can see only my own, just one. However, no IP can be obtained on wlan0. I did not go through the steps I mentioned above to get an IP. When I unload b43 and do the above steps, I see all APs and can get IP by following above procedure. Hence I guess the problem is not with the wlan driver but the DHCP. Let me know if you need any more info.
