hi pmdsp,
i believe i already tried the broadcom BCM57781, if i remeber i correctly it did not work with ML. what is used was this
http://www.osx86.net/view/3089-broadcom_netlink_bcm5778x.html
havent tried if lan would actually work, they said DCHP doesnt work, you need to manually configure it, havent tried, but since mac app store detects an ethernet card, i'm now able to log in.
with sleep, should i try deleting nullcpupowermanagement.kext first?
speedstep, i think is working, opened HW monitor, both cpu 1 and 2 were running at 1518mhz, then when i opened an app, they both ran at 3069mhz, thats it right?
the dsdt you attached, is it for extreme 4 gen 3?
thanks
