The way the kernel tests for an FPU is slightly odd. It first prints
"You have a bad 386/387 coupling"
then tries to get the FPU to respond (can't remember exactly what it
does), then if it gets a response it overwrites the above message with
"Math coprocessor using <method> error reporting."
(hence the ^M). If the FPU responds you won't see the first message
because it's so fast, but if it doesn't then the first message doesn't
get overwritten and you see it. I assume you copied the messages from
a syslog file? Unfortunately both messages will appear in a syslog
file, which no doubt many will find confusing 8-)
