DONT STEAL MAC OS X.KEXT

Question

well, i was wandering around in system/library/extensions to find a solution to my unsolved problem (http://discussions.apple.com/thread.jspa?threadID=2513839&tstart=0) so i thought deleting old soundcard drivers might do it better. while that i saw DONT STEAL MAC OS X.kext file. i was curious. so i dragged a copy of that in my desktop then deleted the original file. could not boot again into mac os x
now that i erased my bootcamp partition to install a fresh snow leopard so that i could modify files. i installed snow leopard, then moved into other partition n dragged dont steal mac os x.kext to system/library/extensions back. but still cant boot the ex-snow leopard partition. is there anything that can be done without formatting the drive. cuz i really i mean really need to use that system. formatting is so lame u know. then loading everything back, i dont have that much of time tho i need to boot it up back again so that i can work . gimme a way outta this plz?
is there anything that can be done? it shud have been booting correctly by now but it aint booting.

When you copied the "Dont Steal Mac OS X" package file back, the permissions might not have
gotten set correctly. Running permissions repair on the affected drive should fix it.
One method of avoiding permission problems when copying system files to their respective
directories is to use the terminal command "cp" to do it.
http://ss64.com/osx/cp.html
note: As of Mac OS X 10.4, the cp command preserves metadata and resource forks of files
on Extended HFS volumes, so it can be used in place of CpMac. The /usr/bin/CpMac
command will be deprecated in future versions of Mac OS X.
Sometimes fooling around with system files may require you to "bless" the boot volume again to get
her to start back up.
boot from your other partition (or system install) disk, open terminal, run the following command:
(from install dvd);
bless --folder /"Macintosh HD"/System/Library/CoreServices --bootefi
if from another bootable partition copy of OS X:
sudo bless --folder /Volumes/"Macintosh HD"/System/Library/CoreServices --bootefi
note: --bootinfo (PPC) option is not supported (needed) in SL. PPC code has been removed in SL.
type:
man bless
(in terminal, to see more info about bless command)
About your soundcard problem:
I had a similar problem. My card worked until I installed Security Update 2010-005. I only
got it working again by removing the update (fortunately I backed up before installing the
update and was able to restore easily). I don't know if that is your issue, but be aware that
occasionally an update may cause a hardware compatibility issue.
