Ingo - could you add

sdev_printk(KERN_ERR, scmd->device, "Whoa - large secor size %d\n",

before the do_div calls, and see what that reports?
Ok, so, drivers/scsi/sd.c looks now as this:
if (scmd->device->sector_size < 512) {
/* only legitimate sector_size here is 256 */
start_lba <<= 1;
end_lba <<= 1;
} else {
/* be careful ... don't want any overflows */
u64 factor = scmd->device->sector_size / 512;
if (scmd->device->sector_size > 2048)
sdev_printk(KERN_ERR, scmd->device, "Whoa - large
sector size %d\n", scmd->device->sector_size);
do_div(start_lba, factor);
do_div(end_lba, factor);
}
... will rebuilt and install it then...
