10.6.6 No Airport Card
Here's a problem that has left me scratching my head... I applied the 10.6.6 update on my 10.6.4 system and everything looked fine. My Broadcom based WiFi card was seen and was working. I was running on a single 2GB memory stick as I had a stick of memory go bad, and meanwhile got 2 new Corsair memory sticks to bring the system back up to 4GB, rebooted 10.6.6 and there's no WiFi found. Remove a stick of memory and it's back. I'm running the 64 bit kernel, and obviously would prefer to have all 4GB of memory in the system. lspci shows the WiFi card as 04:01.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 03)
Subsystem: Belkin F5D7000uk 54G Wireless Network Card
Flags: bus master, fast devsel, latency 32, IRQ 19
Memory at fdcfe000 (32-bit, non-prefetchable)
I'm not sure what else to look at. Any suggestions? The motherboard is a 2.4 revision level, and I've booted in 32 bit and 64 bit with the same results.

Update: Well, maybe this explains it: BCM4320 on 10.6.5

Thank you so much, it took a bit of fiddling but once I realised it was a Kernel issue I got it fixed.
For anyone else with this issue, I used IO80211Family.kext, IONetworkingFamily.kext, IOUSBFamily.kext and mach_kernel from 10.6.4 with everything else stock 10.6.6 and it's running stably with wifi working.

I'm not sure it's worth it to do this much fiddling just to get the AppStore... maybe 10.6.7 will be a fix for it.
