#237: nandflash writes fail with OFW

 This took a long time to track down.  :/

 dmesg attached.  OFW boots the NAND flash, but writes start failing almost
 immediately and soon jffs2 panics.  This was 100% reproducible with both
 usedma=1 and 0; it wasn't working for hours, I flashed from OFW back to
 LaB, it worked straight away.

 I'm having trouble explaining it.  I *wrote* the image to the nandflash
 inside OFW, so it's not that all writes from inside OFW are failing, but
 most writes are.  The video output was full of things like
 "{chown,touch,rm}: I/O error".
