[c-nsp] 6500 hybrid - native conversion crashes

First we (Cisco)  need to update our CatOS/IOS conversion documentation to 
mention that we need to autoboot RP and not set config-register to 0x0 and 
do manual boot.

So, this is not a workaround but working as expected. The documentation 
needs to be updated. I will follow up with the TAC Engineer and CCO 
documentation folks to get the conversion document updated.

In the  olden days (4 to 5 years ago) there used to be some autoboot 
issues and probably this and subsequent versions of the document 
originated from that, and they never updated it.

Even if the sup-bootflash:, is booted from a different filesystem you 
should be able read/boot from it. In most cases you would be able to even 
write to the linear flash. However, to be safe it is recommended to format 
with the new filesystem.
