Went to 10.5.5 and saw some issues. After reboot kept getting bios corrupted/defaulted. My mobo is an EX58-EXTREME so I crossflashed to F13 EX58-UD5 and used d00d's latest DSDT. Also he had a link to applertc patch for cmos reset. That problem was solved. Next problem was after sleep my audio device was gone. I got lucky here in that apparently 10.5.5 overwrote the original AppleHDA kext. Went back to digital_dreamer's kext and that problem is gone. So my sleep works perfect. Rarely do I shutdown/reboot so this was the #1 priority. Audio has pop coming out of sleep but big deal. My shutdown/restart is a little flaky but I'm considering the transition to Yosemite done.
so long and thanks for all the fish digital_dreamer and d00d
