If enough RAM is chopped off users will notice. They tend to complain
when they miss RAM. I don't like panic very much because for many
users it will be a show stopper (even when they are not blessed
with "quiet" boots like some distributions do)
The message in dmesg could be also emphasized a bit with a little
ASCII art (but no <blink> tag in there)
The problem I'm more worried about is if the system will be really
stable --- could it be that the memory controller is still
misconfigured and cause other stability issues? (we've had such
cases in the past). Also I'm not sure we can handle the case of
the MTRR wrong not at the end of memory but at the hole sanely.
