I see from another thread that you now have access to your serial no. again. Good news!
When you go onto the Hyperion website you should find a list of bugfixes. From what I can tell 3.2.2.1 is software only and the latest official ROM version is 3.2.2.
With the PiStorm32 it can use a different kickstart to the one you have as physical ROM chips. I have 3.2 physical chips but softkick to 3.2.2. This might help you if you are swapping between boards; it sounds like the 1260 ROMs you are asking about are modified for a specific accelerator so you could have those on your motherboard and then when you use a PiStorm32, that can override the physical ROMs by having your PiStorm boot with 3.2.2.
