Was just curious as some PS/2 adapters can be quite slow to initialize at boot. I have this problem on my A1200T with Blizzard1260 - disabling the card by pressing '2' is _very_ hard as the keyboard finished its initialization just before the time to press '2' is up.
So nothing happens if you reboot and press esc numerous times?
I have heard of BlizzardPPC users having problem with their flash going bad, so a suggestion might be to reflash the CyberStormPPC flash. It would atleast not hurt doing so.
