I'm not sure if the newly-released version 1.6 will help with this issue or 
not.  But it might.

More system information will be needed before any further follow-up or efforts 
could be made (e.g. what kind of processor).

I've had the same issue on 1.6.1 on Lion.

It seems that it's stricter about file permissions: Write permission on Group 
makes it give that error.

In my case, I've just done sudo chmod -R 755 
/System/Library/Extensions/Soundflower.kext/ and it loaded fine.

Easiest way I fixed it was to go into 
/System/Library/Extensions/Soundflower.kext/ and right click on it, unlock, 
change wheel from "read/write" to "read-only". 

Go into terminal and "sudo kextload 
/System/Library/Extensions/Soundflower.kext" and you're good to go after making 
the appropriate adjustment in permissions.

Thanks, I had the same issue and doing "sudo chmod -R 755 
/System/Library/Extensions/Soundflower.kext/" and then "sudo kextload 
/System/Library/Extensions/Soundflower.kext" fixed it for me.
