I don't know what you mean by a dead kernel here. If, say, the e1000e
device driver is crashy, irrespective of what you use (netconsole or
syslog), there's not much help. In this case, you'll then have to resort
to serial console.

Because it fills the gap in between "kernel load" to "real init start".
Imagine a scenario where as soon as the disk driver is loaded, the
kernel panics. How would you debug that ?

PS: It is just a suggestion. Your patch is still valid, just not very
relevant to the use cases.
