In drivers/scsi/sd.c:read_capacity_10(), you'd have to change the values for sector_size and lba. Obviously sector_size should be 512. Goodness knows what lba should be -- it's supposed to be the total number of sectors minus 1, but do you know how many sectors the thing really has? And who knows if the flash device will work even after you make this change...
