I used the Control Panel to change my kernel from Ubuntu 14.04 x64 vmlinuz-3.13.0-37-generic to Ubuntu 14.04 x64 vmlinuz-3.13.0-40-generic.
The Control Panel now shows Your droplet's current kernel: Ubuntu 14.04 x64 vmlinuz-3.13.0-40-generic
But running uname -ri on my droplet gives 3.13.0-37-generic x86_64, so I think the kernel has not actually been updated.
ls /lib/modules shows 3.13.0-37-generic 3.13.0-40-generic
I have rebooted and apt-get update / upgrade / dist-upgraded several times, to no avail.
Thanks for any help!

This question was answered by @ryanpq:
Just to be sure the state change was picked up by the hypervisor I’d recommend running a
poweroffand then booting the droplet from the control panel.
