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...
