Though support since from kernel 2.6.29.x has been improved, it is still a limited card - for example, you won't get any noise signal level output info and the bitrate will always be 1MB/s untill some intense internet traffic; if you manually change the bitrate to a fixed value, it's likely that the connection will keep dropping untill you set it again to auto.

But, nonetheless, the card does it's job and get me around the web without problems. Connection is stable and I do not get disconnected from the AP. It's a good card with a very good support from the guys at wireless.kernel.org.

Alternative: You could use the non-OpenSource driver from broadcom, the Broadcom Hybrid STA. It has complete functionality and will show you noise signal level and make it possible to set the bitrate, but you'll have a tainted kernel flag.

I had a lot of trouble getting this card running. It came with my HP Mini 110-1012NR netbook. If I had known that the netbook came with this device, I would not have bought it in the first place.

First, the b43/b44 drivers didn't work very well. For some reason while using the b43 driver, I was able to connect to my home WLAN (encrypted connection), but I wasn't able to connect to any public WiFi hotspots. The only way I can get it to work at all is if I'm using the Broadcom STA driver (closed source) and even then, the iwconfig utility doesn't tell me what access point I'm connected to unless I ran it as root. This meant jumping through extra hoops if I wanted to display such information in Conky or similar programs.

Before you buy, call the store and ask if the machine ships with this card, and don't buy if it does. If you already own a machine with this card installed, and you have steady hands (and some pretty small screwdrivers), you could attempt to remove the card and just use a USB WiFi adapter.
