Hmm, I havn't tested the CSB stuff for some time and I have only used it
with the old board containing the PXA250. As there was no real customer
project behind the board and I used it mainly for testing the network
chip I didn't investigate the flash stuff too deeply.

Having just a short look into it it looks like a bug which didn't turn
up because I didn't have a faster processor at that time.
