rocminfo uses lsmod to check for loaded drivers. Use of sysfs is
possible but sysfs' stable interface does not allow for easy parsing.
Use of lsmod avoids needing to walk the sysfs tree and avoids issues
of permissions to examine sysfs.
Both Debian and Fedora list lsmod under kmod. Presumption is that
CentOS and RHEL also follow this.
