Incredible, thanks for the lan driver tip, that did the trick. My machine is waking up now, though there is one last issue: I have one display connected via DVI and one via HDMI. The DVI display wakes up while the HDMI one is staying dark. In System preferences etc I can see that the Display still is connected, windows are on it and I can move my mouse over the workspace but the display is dead. Is this a known problem for ATI 5770 cards?
Bios version F2 and lnx2mac's RTL81xxx driver that came bundled with ######, not sure which version that is. Trying the newest 0.90 beta now and will report back!
Btw what is the preferred way to enable audio with this DSDT?
Sorry for reviving such an old thread but I have the same board and experience wake up problems. I use the DSDT Mald0n posted in this thread but my machine fails to wake up from sleep :/ Any hints?
