How can i Make check boxes enabled, where multiple options are given. Help needed urgently.

Hi,
I am using feeds module in my project.
In my record i have a set of information which is as follows

name : Suresh
city : Chennai
hobbies : Reading , Hearing Music , Playing cards.

The above is a sample record of a user.
which i have in Excel format.
Each user must have their own node.(i.e it should create a new node)
I achieved this with feeds module.
Here " hobbies: " will have some Options which
are constant where users are expected to check his hobbies.
Now i need to know whether it is possible with feeds module to
get these ?
Please someone help me.I tried mapping the field name to feeds but
its accepting the values but it is not checking the boxes.
