If you are willing to work at it, you can run MorphOS on your A1 now, according to some felgercarb I heard on the net.
The only reason MOS cannot run on the A1 is that little uBoot BIOS. If you were to, say, flash an OpenFirmware to replace the uBoot's FlashROM, it would then theoretically be possible to get MorphOS onto the A1.
