 Oh, got it now, 9.3 isn't a standalone release, it's an update.

 I don't know any other table that's of any use in user space.  I get EIO
 on ioctl(EFIIOC_GET_TABLE), don't see the patch returning it explicitly,
 but in here:

 It looks like first two parameters must be swapped.  However, I still
 get EIO after doing this.

 Yes, that's correct.

 That's essentially what this report is about.  Docs say "push to
 pkgsrc-wip then send bug report to move to pkgsrc", the port is already
 in pkgsrc-wip.
