These options are ignored. linux/fs/ext2/super.c from 2.2.18-pre17:
/* Silently ignore the quota options */
else if (!strcmp (this_char, "grpquota")
|| !strcmp (this_char, "noquota")
|| !strcmp (this_char, "quota")
|| !strcmp (this_char, "usrquota"))
/* Don't do anything ;-) */ ;
else {
printk ("EXT2-fs: Unrecognized mount option %s\n",
this_char);
return 0;
}

Don't mount so many filesystems, or don't use so many no-op options :)
