You can get away with using the same mountpoint for both types of disk
by mounting with 'mount /mnt/zip'. the ext2-disk gets the permissions
of the mountpoint and the dos/vfat-disk gets the permissions by
the options umask, gid and uid

/dev/sda1  /zip  ext2  noauto,user,async  1  1 
/dev/sda4  /zip  vfat  noauto,user,async,gid=35,umask=007  1  1

Besides that way there's the 'auto' thing:
>From 'man mount':
 -t vfstype
              The argument following the -t is used  to  indicate
              the  file system type.  The file system types which
              are   currently    supported    are    listed    in
              linux/fs/filesystems.c:  minix,  ext,  ext2, xiafs,
              hpfs, fat, msdos, umsdos, vfat, proc, nfs, iso9660,
              smb,  ncp,  affs, ufs, sysv, xenix, coherent.  Note
              that the last three are equivalent and  that  xenix
              and  coherent  will be removed at some point in the
              future -- use sysv instead.

              More than one type may be specified in a comma sep­
              arated  list.  The list of file system types can be
              prefixed with no to specify the file  system  types
              on  which  no action should be taken.  (This can be
              meaningful with the -a option.)

              For example, the command:
                     mount -a -t nomsdos,ext
              mounts all file systems except those of type  msdos
              and ext.
