Log: Fixed Terminal crash: initialized the cursorPos variable to zero.
Due to this bug, cursorPos was used with uninitialized random data,
resulting in a possibly erroneous memory write reference. The result
was that FreeNOS couldn't boot successfully on bare hardware. This patch
solves that issue.
