There isn't presently an obvious way because the builtin
`read-file-name' was changed to bind `completion-ignore-case' to t
before calling `completing-read' on DOS, NT, VMS and MACOSX systems.

You could partially revert that change to Fread_file_name, eg:

--- fileio.c	22 May 2004 23:17:17 +0100	1.505
+++ fileio.c	23 Jun 2004 17:19:07 +0100

     }
 
   count = SPECPDL_INDEX ();
-#if defined VMS || defined DOS_NT || defined MAC_OSX
+#if defined VMS || defined DOS_NT
   specbind (intern ("completion-ignore-case"), Qt);
 #endif

Maybe there should be a `read-file-name-completion-ignore-case' user
variable ?
