Hi
check this link,
http://gentoo-wiki.com/HARDWARE_Dell_Inspiron_1520#Wireless_Network

It says that
<snip>
You should install the Windows driver from Dell if you would like to take advantage of the full bandwith of your WLAN card (meaning 54 MBit/s).
!!FIXME!! If you would like to use the kernel driver, probably you can but only with limited (11 MBit/s) bandwith.
</snip>

BTW,
  I am more interested to get things working. Quality would be my second priority.

Thanks,
flukebox

Don't know what you mean exactly by "full features". I have used them in
infrastructure mode with no problems (wpa2). However, here's the
official page:

http://linuxwireless.org/en/users/Drivers/b43

according to

http://linuxwireless.org/en/users/Drivers/b43/devices

your card (14E4:4311) is supported.

You need the firmware for the card, and the appropriate *-cutter tool to
extract the firmware from the driver (it's in portage).
Detailed info and step-by-step instructions are provided in the
aforementioned page.
