Firstly check to see if your app is growing in size by using "ps"
or some other on-box tool. If it is then there is a leak regardless of
what valgrind says ;-)

This will only help if your system is losing memory and not your app.
Of course it will usually give you more free memory and may mask the
effect of your app leaking for a while.

Are you running 2.4 or 2.6 ?
For 2.4 it should appear as an option under kernel hacking. It will be
called "CONTIGUOUS_PAGE_ALLOC" or "Non power-of-2 kernel allocator" and
enables kmalloc2.
If you can't find it it may be because your arch does not include it in
it's top level Config.in (linux-2.4.x/arch/XXX/config.in). It is
currently included for:
armnommu e1nommu frv h8300 m68knommu microblaze v850
If your arch isn't listed then look at one of these for an example of
how to add it.
There is no such option under 2.6, you may like to try SLOB or SLUB
to see if they help,

Your mail is not big and your english is not bad ;-)
