in this case - is it true that providing the kernel crash log buffer to the 
next running kernel - is actually more important than just giving it to the 
bootloader? (Since the bootloader may not have the facilities to 
email/post/netcat it to a developer - like the next running kernel might?)

In this case - the Bootloader being able to read the buffer, understand that 
there was a crash, and be able to pass the buffer (with the crash message) 
into the next running kernel - where that kernel can package it up and do 
anything it wants to it - would be a requirement?
