Maybe you want the 'backupcopy' option, to tell Vim to just modify the original file, rather than renaming the write backup file to replace the original. See :help 'backupcopy'. I'm not CERTAIN this will work, but it at least stands a chance.

It also might be possible to hook a chmod command into a BufWritePost autocmd to restore permissions read in during a BufWritePre autocmd, if 'backupcopy' doesn't help.
