Inspecting the code reveals a few more limitations like:
1) ptl_am/cmarwu.c looks x86_64 specific (has specific ASM code)
2) various places in the code expects pointers to be __u64 compatible
3) support of sse4.2 is required

About the latter, it might be a good idea to build-depend on sse4.2-support
which exists only on architectures where it is supported (currently, any-amd64
and any-i386).
