Comment:

 Re-opening because I have seen an IRC report that suggests dfu-util -U
 data corruption is still present with production GTA02, and because I can
 reproduce it on my production GTA01Bv4.

 Prior to this test I executed "nand erase kernel" from the u-boot console.
 I then downloaded a kernel image, uploaded it to a different filename, and
 compared the results. As shown by the following log, no errors were
 reported but the uploaded file differs from the downloaded one at byte
 offset 12289.

 Host PC is Intel x86_64, OpenSuSE 10.3. u-boot is u-boot-
 gta01bv4-1.3.1+gitr52+dc633f4be2527f844158aa5085c278b0c3039d3f-r0.bin and
 dfu-util was downloaded today from
 http://buildhost.openmoko.org/daily/workdir/deploy/glibc/tools/dfu-
 util-0.1+svnr4160
