clearest guide I've seen for the 1000HE. Thank you. 10.6.1 appears to run much quicker than the base 10.6 SL. Having a bootable backup AND the tweaked install USB are critical because mistakes happen.
I had difficulty with 10.6.4 - followed your guide using the newest Netbookinstaller. The result was booting through almost to the desktop. Freezes right at the desktop before the Dock appears. I did not update DSDT file. I only updated kext using Kext Helper (the updater from /Extra didn't work for me either)

I have a 10.6.1 with working ethernet, sound, bluetooth. Works great. Maybe I should just be happy, but if you have a suggestion to get to 10.6.4, I'd appreciate it.

cheers
