The board (Picture Elements JSE) is a PPC405GPr with a SystemACE
attached to a compact flash socket. I've tested your patch with
an off-the-shelf SanDisk 64MB CompactFlash card, and also with
a card repartitioned (on my Linux workstation) with fdisk to have
two primary partitions.

Without your patch, I can list the fat partition (which is the first
partition) and load files from it just fine. With your patch, I get
the error above and nothing works.

Here is a raw dump of the partition table (via fdisk) for an
off-the-shelf disk, followed by a similar dump for a repartitioned
disk.

Off the shelf...
