I used Sticks <= 256 MiB for testing.

Hm, I'm skeptic. Do you know wich OHCI driver is used in your
U-Boot? The newer generic one or the older mpc52xx specific?
IFAIK the generic one is used since U-Boot v1.3.0-rc3. I only had
problems with the generic one. No stick I tested does work with
this driver - but I haven't tested sticks >= 512 MiB, though.
