This should be in /etc/udev/rules.d/10-local.rules, so it is processed
before the default rules, but that's not the problem here.

That's because you are trying to mount the whole device, not the
partition.

Now you are mounting the partition.

Yes, it's not a block device. Change the NAME part of the rule to
NAME="istick%n" and mount /dev/istick1. Or just set up a rule to match
the partition. This is the sort of thing I use for a USB stick

BUS=="usb",  KERNEL=="sd?1", SYSFS{idProduct}=="0845", SYSFS{idVendor}=="08ec", NAME="gigabyte", SYMLINK="%k usb/gigabyte"

I don't use fstab, but let KDE/HAL/pmount mount it on /media/gigabyte.
But I could put /dev/gigabyte in fstab if I didn't want automounting.

Any sufficiently advanced bug is indistinguishable from a feature.
