Yes, but what's the point of having 100mb of unusable space?
What used to happen is the 01mvdalvik script would move the dalvik cache to the same partition your market downloads would go to. This made it appear you had lots of extra space since dalvik cache was moved, but the Market would check the download folder for space, and since dalvik was in that partition, the Market wouldn't allow you to download/update and gave an insufficient space error.
Now with 01mvdalvik functionality removed, the dalvik-cache files stay in their normal directory, which is your internal space is taken up. You can use TB's integrate dalvik to system function to fix this, just be sure to undo it before you install another ROM or you'll have to reflash gapps.
You can also use any of the *2sd scripts, but I do not support them, too many issues with so many different versions. JerryScript
