SOLVED! Broadcom Wifi enabled in 10.6.7

SOLVED!

Did some more searching and found the following post at http://www.insanelymac.com/forum/index.php?showtopic=253373&hl=airport which references another post at http://www.insanelymac.com/forum/index.php?showtopic=244614

The relevant part:

I found a better way of fixing this problem, apparently the kext doesn't load because it only supports up to 1GB of RAM, so adding "max_valid_dma_addr=1024" to your kernel arguments fixes the problem.

Step-by-step:
Open Finder and navigate to com.apple.Boot.plist
Add max_valid_dma_addr=1024 to the kernel flags."

So my com.apple.Boot.plist files (inside Extra folder and /Library/Preferences/SystemConfiguration/com.apple.Boot.plist) now includes:

<key>Kernel Flags</key>
<string>arch=i386 max_valid_dma_addr=1024</string>

So now I have wifi working in 10.6.7!

Hope someone finds this helpful. Now I just have sleep to fix.

Hi, first post.

I've been trying to upgrade my Hackintosh from a working 10.5.7 install with a clean Snow Leopard install. I've been experimenting with different wifi hacks, when I noticed the following.

At random I used the new 3.5.2 MultiBeast on a fresh 10.6.3 install with the wifi card installed. On reboot, I noticed that my wifi card was working! However, doing the 10.6.7 combo update and then reapplying the same MultiBeast settings didn't bring the card back. Also, going 10.6.3>10.6.7.>MultiBeast didn't work either.

Currently, going the 10.6.3>10.6.7.>MultiBeast 3.5.2 route I can get sound, graphics and ethernet working. The last two things I need to work on are wifi and sleep.

Any suggestions on how to keep my wifi working after a 10.6.7 update?

My system:
Gigabyte GA-G31M-E2SL rev 1.1 bios F5
Intel E5200
2x2Gb DDR2 800 RAM
ZOTAC NVIDIA GeForce 7300GT 256 MB DDR2 PCI Express
WD 640Gb Scorpio Black SATA
NEC IDE DVD-R
Buffalo-branded Broadcom BCM4306 802.11b/g Wireless rev 03 [System identifies as 14e4:4320]

MultiBeast 3.5.2 options used:
System Utilities
VoodooHDA 0.2.72
NVEnabler
ElliottForceLegacyRTC
EvOreboot
FakeSMC
FakeSMC Plugins
NullCPUOwerManagement
Chameleon 2.0 RCF - Prerelease
32-bit Apple Boot Screen
MacPro 3,1 System Definition

I have had the system running stable at 3.3gHz since 10.5.5, with a 266 bus and the RAM at 1066.

Please help me finish!

I have the same problem i tried what folfin said and it did not work.
It's been a minute how do i add to the kernal flags?
do i ad like this just under <key>Kernal Flags</Key>

Like this
<key>Kernal Flags</Key>
<string>max_valid_dma_addr=1024</string>

or

to existing...
<string>arch=x86_64 max_valid_dma_addr=1024</string>

Thanks-J

so i added <string>max_valid_dma_addr=1024</string>
to my boot.plist and no success.
I ordered the D-LINK DWA-556 11N, ill see how it goes when i receive it.
