Mosslack / Kaido, thanks for your past comments. Helped a lot in getting to 10.6.3.
Recently reinstalled Snowleopard, ran update and found that now apple offers straight 10.6.4. combo for 10.6.0 system. So gave it a try, but started having kernel panics.
So now am back to 10.6.0.
I put one this in the boot.com.plist <string>pmVersion=20</string>
since this was already in the plist. <key>Kernel Flags</key>
so do I need to put them exactly like this and both of them, even if one of them is already there?
<key>Kernel Flags</key>
<string>pmVersion=20</string>
What kexts do I have to remove/install?
And how do I remove or install them. Just drag them out of extra/extensions?
my E/E folder does not have applehda or vodoo kext. but it does have sleepenabler.
Mosslack since my built is based on the files I download from your googlegroup, so i am guessing I will need to remove sleepenabler and replace it with the one suggested on your page?
any other steps before I hit the install button for 10.6.4 combo update? don't wish to keep repeating installations only.

hopefully can start using Sleo more often for work.
edit: ok, so could not wait and removed the sleepenabler kext from E/E, and installed the one suggested by mosslack's google.code website. then installed 10.6.4 combo. hack boots fine, but gets stuck at the blue screen just before showing main desktop. Any suggestions?
