I did a search on the net and found that you macbook has 1 GB RAM and 
144 MB VRAM. In my opinion first you should have at least 2 GB RAM if 
you want to operate well under 11.04. I have the same version of Ubuntu 
installed with 2.8 GB RAM  and it work just fine. BUT if want to use 
virtualbox running oneiric ocelot or other any new OS I must have 4GB 
RAM installed. After you have 2-3-4 GB RAM start thinking about HDD.
