Take a look at linux/Documentation/laptop-mode.txt on any recent -mm
kernel.
The short description is that it allows you to force the filesytem into
a mode where it doesn't flush things to disk. The risk is increased
loss of data if you crash, the gain is better battery life on laptops.
The docs include a sample control script and other details.
The reiserfs patch is quite small, just making sure the journal honors
the flush timings requested by the rest of the kernel.
