	You wouldn't need read support for a stat.  Just opening with NULL 
permissions would be sufficient for a stat.
Open() in LSD associates an fd with an actual file, and permissions to 
do stuff.  As long as you know the file exists, and can stat it under 
*NIX conditions (As a baseline), you can open with NO permissions, and 
stat that fd.
