It is true that by making the kernel oops message more verbose, s2c
can be made way simpler.  However, dependence on standard object tools
or perl is already assumed and avoiding it doesn't really buy
anything.  I really like the idea but unfortunately I'm doubtful that
it will be able to go upstream in the current form.  The suggested
solution (extending markup_oops.pl) won't be too much work, most of
functionality will remain the same and will have much higher chance of
getting included.

Thanks.
