I have an HP Mini 210-1000 with a troublesome [14e4:4315] LP-PHY rev 01 wireless card. I've done some analysis of the b43 driver's performance with different firmware versions [1] in response to discussion [2] about the Archwiki documentation on obtaining the firmware [3].

I also have a MacBookPro7,1 and created the first version of the Archwiki page for it [4] in hopes of gathering information, but have since given up.

Yay linux! :)
