I had removed network-manager as soon as I installed Ubuntu 10.04.

Earlier I used to do the following to connect (successfully) on command line:
iwconfig eth2 essid NASA
dhclient eth2

Now that WPA2 encryption is enabled, I tried this, but failed:
iwconfig eth2 essid NASA key hunter2
dhclient eth2

with error:
Error for wireless request "Set Encode" (8B2A) : invalid argument "hunter2"

Where am I going wrong?

lspci gives:
02:00.0 Network controller: Broadcom Corporation Device 4727 (rev 01)

lshw -C network gives:

*-network

Edit 1: As suggested by CYREX, I tried WPA directions given in:
http://ubuntuforums.org/showthread.php?t=571188
In the command:
sudo wpa_supplicant -D wext -i eth2 -c /etc/wpa_supplicant.conf
I used wext as the driver.

When I run this command, the following happens:
Trying to associate with 00:24:b2:39:f4:c6 (SSID='NASA' freq=2462 MHz) ioctl[SIOCSIWAP]: Device or resource busy
Association request to the driver failed

I tried both his WPA1 and WPA2 stuff. In either case iwconfig eth2 gives Encryption key: off.

I made this one: How to connect and disconnect to a network manually in terminal?

But i think it won't work since i later found out that when you put a WPA key, the whole thing gets a "little" complicated. Not so easy as iwconfi wlan0 key s:password for like WEP security. I then found out this HUGE post which has in detail information that worked in my case for WPA and WPA2 using PSK (At least in my case) I hope it helps you too:

NOTE: Make sure your card supports WPA. Happen to one of my students that he spend a week trying this and it did not work since his card did not support WPA (It did not even have anything WPA related).

More Specific link about WPA2 -> http://ubuntuforums.org/showthread.php?t=607410 Good luck, let me know how it went.
