It's not a 2 byte binary. It's a leading ascii SOH and a standard ascii char '0' ... '7' or 'd'.
#define KERN_EMERG KERN_SOH "0" /* system is unusable */ #define KERN_ALERT KERN_SOH "1" /* action must be taken immediately */ etc...

No it doesn't.
It's not triggering that because devkmsg_writev does prefix parsing only on the old "<n>" form.
