Yes, the kernel image is not updated by 3.2.0 firmware package, this is certain.
If you're right, so
1. kernel is the same for Mini, Glo and "low cost" Touch
2. their kernel is the uImage file
if so, there's a bug in the update script.
But we can't be 100% sure. uImage could be the kernel for Mini and Touch. Glo kernel could be remained unchanged, so it didn't need an upgrade. That's why I asked you if in previous firmware packages there was an uImage-E606B0 image file.
I can't see what recovery uImage contains:
PHP Code:
# mkdir /mnt/recovery-fs
# mkdir /mnt/recovery-kernel/
# mount /dev/mmcblk0p2 /mnt/recovery-fs
# mount -t ext4 -o loop /mnt/recovery-fs/upgrade/ntx508/uImage /mnt/kernel-recovery/
mount: mounting /dev/loop0 on /mnt/kernel-recovery/ failed: Invalid argument
