Booting into older kernel (2.6.32-15-generic) isn't a problem. 
(and wait for further upgrades to sort this out)

But if we really want to boot into 2.6.32-16-generic, then try one of the 
following......

[1]
Boot into recovery, select boot normal, at prompt, login and type either
'sudo kdm start' or 'startx'  (preferably the former)

[2]
At blank screen (after attempting to boot as usual), press
'alt' + 'ctl' + 'prt scr' + 'k'


I'd recommend [1].
