No.  Cygwin already can access files on the file system, it just can't
access facilities not provided by the driver.

No.  First, the driver is communicating with the Windows kernel.
Cygwin is using OS function calls for file access.  There's no direct
talk between driver and Cygwin.  Second, what the driver provides to
Windows is available to Cygwin.  Since the driver doesn't support POSIX
permission <-> ACL translation and symlinks on the OS level, it won't
help to communicate with it directly.
