Thanks for looking at this.

If kernel.release doen't exist KERNEL_RELEASE is empty, thus all args
for install.sh shift one arg left. Putting it in quotes avoids this.
Noticed this since the first verified file in install.sh ($2) should
be the image file but was already System.map ($3).

Will splitt the patches and resend.
