Not only does ksymoops support it but some architectures already do
this. Mind you, they are not consistent :(

Alpha: Code: 44220001 f4200003 46520400 <a77d9c38> 6b9b4a40 a44803a8 42425401 42c10403 40603401
Arm: Code: e7973108 e1a02423 (e5c42001) e5c43000 e1a02823

If any instruction in the code line is enclosed in <> or () then
ksymoops assumes that the first byte is EIP. Otherwise the first byte
of the line is EIP. Anybody want to update i386/ia64/mips/... oops code
to dump context around the failing instruction? Maximum of 64 bytes in
the code line please.
