plotting dates on x axis with labels auto generated for 1st Jan each year?

Hi, I'm plotting monthly data (generally the 16th of the month) over 20 or more years with the dates held as datenum's.
I'm generating my plots in code.
Does anyone know if there's a way to force/tell matlab to just have yearly points on the x axis, ie datetick('x',24,'keepticks'))
BUT have these autogenerated to the beginning of each year? So while the label will read say "2007", that point will be "01/01/2007".
Thanks for any help,
Tom.

EDIT (0:20 MDT 09.12.2011)
input data (e.g.):
n = 22*12-7;
datedata = datenum(bsxfun(@plus,[1990 12 16],[zeros(n,1) (0:n-1)' zeros(n,1)]));
solution:
n2 = diff(year(dte([1,end])));
x = datenum(bsxfun(@plus,[1991 1 1],[(0:n2-1)' zeros(n2,2)]));
plot(datedata,rand(numel(datedata),1));grid on
set(gca,'XTick',x);
datetick('x','yyyy','keepticks')
