Hi Gavin.  Check with the provider.  Every VPS provider that I've looked 
at closely allows console access of some description.  For example, Linode 
allows access to a serial console via ssh to an IP not on my VPS.  I 
needed to put in an RSA key pair for this to work.  They also offer an 
AJAX console through their managememnt interface if you are really stuck.

If the VPS provider expects you to reinstall after an error like locking a 
firewall then you need a new VPS provider.
