Upgrade to Hijack v387 and reboot. No more need for the flash_0e000 thing that way. But the diagnostic memory test is gone in that version -- it still does a ramtest, but just silently ignores the extra memory if it fails the test.

You can check for this by connection with serial, and hitting Q or control^C to exit the player, and then do: cat /proc/meminfo

It should look like what I posted earlier in this thread if all 32MB is working.

EDIT: Specifically, there should be a line like this in meminfo:

            MemTotal:     31176 kB

Cheers
