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.
