I will send out the first rev of patch today to address the
functionality issue. This patch will not worry about exporting the NAT
bits in r8-r11 to user. So, the ld.fills will be replaced by simple ld.

Though, as per the disussions with David, there is scope of further
optimization in the way we are saving/restoring r8-r11 in this code.
This will probably need little more analysis to ensure best
placement/scheduling of new code. Will send that later...

Thanks,
