U-boot apparently has a very simple memory checker, this doesn't help
me as I don't have serial access. I have now re-compiled the 2.6.33
kernel whilst the device has been on the 2.6.33 kernel 4 times now
*without* an *error*. I also ran memtester for a while using most of
the memory on the device, without invoking the oom killer.

I will re-run these tests on the 2.6.32.7 kernel soon.
