There are a few ways of doing that.
You could do it via the OVH manager, provided the kernel is available there (not 3.7.x in my case):
Log into your OVH Manager and select the server. From the available menu on the left hand side, under the heading "Dedicated servers", select "Services" and then "Netboot".
You should be able to select between hd, rescue-pro, vKVM or the available kernels - just select the kernel you need and reboot the server.
This is also easily reversible by following the same procedure.
Alternatively, you can download the kernels directly onto your server:
During the update-grub command, you should see that it found linux image /boot/bzImage-3.7.10-xxxx-grs-ipv6-64 (make sure it does). The changes will take effect once you reboot the server (use the reboot command). You can double check with the uname -a command that the new kernel has been loaded.
Note that in above example, you will be using OVH's GRS-hardened kernel.
Furthermore, note that the "echo" commands in the email you've quoted are only valid until the next reboot.
