Label half the extensions Yellow and then drag them into the Extensions Folder. Restart and pray during boot.. If it boots, change to labels from Yellow to Green. If it doens't boot, Remove half the extensions and label the remaining ones Red. Reboot and pray some more. If it boots, change the Red label to Green. If not, remove the Red ones and replace with the Yellow ones. Reboot, pray and if it boots, change Yellow to Greeen, etc. etc. Then repeat with the second half.
There is also a utility, which I believe is called Extensions Manager, which makes this even easier.
