Wow, I want to live in that world you seem to be living. I rest my 
case.

I find a way to handle it in the kernel. So far, I was quite 
successful in doing this for 440 (I just sent a patch for one of such 
erratum upstream).

I can imagine doing this for CDS for example. 

Kumar, you seem to insist that it's easy to update firmware in field, 
it's not. I've been doing this stuff for many years, Dan - probably 
for decades, but you refuse to listen. 

What you will end up with is that that small amount of embedded people 
who bother to contribute something back will stop doing this. We are 
more than capable of maintaining our internal kernel trees :).
