not really.
All RISC based designs need the alignment so that the CPU can fetch a CPU word in one go. CISC based designs do not have this limitiation.
I also do not know of any other CISC based design which made it to mainstream.

Which of the architectures FreeBSD supports (if any) have strict memory
alignment requirements? (in the sense that accessing a 32-bit integer
not aligned on a 32-bit address results in a hardware trap/exception).
I know, they are 64 bits.
