Thanks, I like that header. :)  No need to sanity check yourself.

I'll have to adjust to define both 32-bit and 64-bit offsets.  Ok to use
just SMRAM32_OFS_xyz and SMRAM64_OFS_xyz?  No need for LO32 and HI32, in
particular.

The one problem is that I am doing math on the offsets in some places.
It would suck to save/restore 16 registers manually.  Any suggestions?
I will probably send v1 for review without the offsets.
