BCM4312 ... can't get it working on SL 10.6.6

I am installing OSX on an HP mini 110. I have everything working - sound, Ethernet, video, etc. - except the Wifi. I am running 10.6.6 and using the hacked kernel found on these forums for the Atom processor. Everything works beautifully except Wifi.

 

I've done a lot of reading on the HP mini's stock Wifi card, which appears to be a Broadcom BCM4312 based device (14E4:4315 PCI). On another forum I found a lengthy post that seems to indicate that the Wifi card had two or more revisions that share the same PCI vendor/product ID, and this may be the problem we're facing.

 

I have tried the Broadcom info.plist patcher, and an IOPCIFamily.kext I found on here. Neither enabled the card. The card does now appear under PCI Devices under System Profiler, however I am still unable to get it to actually work as an Airport device. Under the Driver Installed column, it reads "No" for the wifi card.

 

The following is also appearing in the console:

  1/16/11 12:14:34 PM		   kernel  netkas presents fakesmc, a kext which emulates smc device

 1/16/11 12:14:34 PM		   kernel  Kext com.apple.iokit.IO80211Family - library kext com.apple.iokit.IONetworkingFamily not found.

 1/16/11 12:14:34 PM		   kernel  From path: "uuid", 

 1/16/11 12:14:34 PM		   kernel  Waiting for boot volume with UUID 41A7DDBA-E7DC-3B17-AB93-BC4CA714EA28

 

 

 

The laptop does have a "hardware" Wifi power switch, it's a momentary switch like the power switch, and under Windows it turns the radio on and off. Pushing this switch under OSX or during the BIOS POST seems to have no effect. Under Windows, the switch lights blue to indicate Wifi is on, and orange to indicate it is off. When I boot OSX, the Wifi light is on and is blue.

 

OSX acts as if no wifi card at all is installed. Nothing in Network Prefs at all, no wifi icon on the menubar. This makes sense since it appears the Apple broadcom extension won't load

 

Is there any way i can get this to work? Thanks!
