Yes, it's exactly what i meant...

I'm currently re-evaluating the case 18 stuff. Maybe Jurijs proposal about
checking for unaligned access using a decoded opcode might me faster than
dereferencing 3 page tables and having to decode the opcode anyways to
check for read vs write access...

The only question that remains is if the paging code will handle a
recursive trap gracefully (i.e. when the unaligned access emulation code
traps again because of a page fault).

Cheers,
Jochen
