Stuck in a Safe mode crash loop with a Cracked Screen

My Mac fell over yesterday and landed on my DS. It now has a crack in the lower middle of the screen, causing some lines to run across the screen. It still works fine other than the fact that it has some kindof fatal problem with safe mode, that i have no idea how to fix.

Can someone help me? I would much rather get past the safe mode first before handing out money to fix a computer that wont work. I also have some work and software on that machine i don't know if i can replace. But am i going to have to just face the truth and give it up? I really hope that there is another way.
