Thanks for looking into this.
I do not believe that the nvidia drivers are the issue. There aren't
any nvidia drivers on the ubuntu HVM AMI, as far as I can tell. I had
to download them from nvidia's site and compile/install them. I even
had to download the kernel sources to compile the drm module which the
latest nvidia driver (331.49) requires and which isn't included in the
AMI, a la <https://devtalk.nvidia.com/default/topic/547588/>
Here's what I see on a freshly booted Ubuntu 12.04 HVM AMI:

On a side note, I just tried launching the debian 7.4 HVM AMI on
several different instance types for comparison, but I haven't had
1. I was not able to get a system log to retrieve the host ssh public
key, even 20 minutes or more after launch. I tried this in both
us-east-1 and eu-west-1.
2. I blindly accepted the host fingerprint but was denied access when
logging in as user admin with the configured keypair.

If there are "other issues," I infer from the lack of any other
explanation that they must be relevant. Can you elaborate, please?
