Allow +2 nameserver entries for dns= boot option

[lvdh]

Would this change be sufficient to allow more than two nameservers to be entered at live boot? (using the 'dns' boot option)

Apologies for my ignorance if more changes are necessary to solve this problem. Any pointers in the right direction are very welcome, I'm more than happy to learn.

For reference, this has been discussed in issue 1234: http://bts.grml.org/grml/issue1234

FYI, make test does not show any possible problems for the affected files;
