Thank you very much for your response. I will investiage
console.perms, but I guess I will, rather, have to find a way to give
the user those permissions *outside* of console.perms.
However, I greatly appreciate the information. I will search further.

This isn't a VNC issue, it's a permissions issue.

You want to check out:
man 5 console.perms
By default Red Hat (an probably other distros, but I'm not sure) is set to
give the user logging into the console certain permissions to devices,
then revert back to a default when the user logs out. These default
settings can be changed in the /etc/security/console.perms file.
