You have with laptop_mode the same problem than with noflushd (you're losing 29 minutes of data if your laptop crashes and the laptop_mode timeout is 30 minutes). Where the laptop_mode shines is in its mechanism to group write access every time the HD has to spin up (for a read for instance)

AFAIK, on ext3, the commit interval can't be changed. So, every time a process write sth on disk, the journal commit occurs physically within something like 10s. Moreover, without noflushd, the kernel buffers are flushed every 30s (or less, I can't remember) Try mounting you partition using
