Which specific problem is this fixing for you?

you say that atime is ignored; but:

default mounts:

[root at inode test]# echo foo > atimetestfile
[root at inode test]# stat atimetestfile
Access: 2009-01-30 04:36:47.470348714 -0600
[root at inode test]# cat atimetestfile
foo
[root at inode test]# stat atimetestfile
Access: 2009-01-30 04:36:57.450339777 -0600

remount as noatime:

[root at inode test]# mount -o remount,noatime .
[root at inode test]# stat atimetestfile
Access: 2009-01-30 04:36:57.450339777 -0600
[root at inode test]# cat atimetestfile
foo
[root at inode test]# stat atimetestfile
Access: 2009-01-30 04:36:57.450339777 -0600

it would appear to be working...
