NAND on MV78100

I am currently working on board support for a Marvell MV78100 based
board. The MV78100 uses the same Orion SOC components as e.g. the
Kirkwood which is quite well supported from OpenRD and SheevaPlug.
After some struggling I got the Orion NAND driver working, it detects
the NAND chip properly (512MB) and assigns a partition. Everything seems
OK so far.
But when I read from the device, e.g. just by "cat /dev/mtdblock1 | wc
-c" it starts to fail with "uncorrectable error" after exactly 1MB
This seems pretty strange to me and I have no real idea where to look
for the problem. I have the Orion NAND driver working cleanly with the
very same kernel version on a Kirkwood based board without problems.
Any hint on where to look would be *very* much appreciated ;)
