If you (and the code) are absolutely certain that a particular error instance
is totally due to the BIOS, then stick the words "BIOS ERROR" into the printk().

Problem solved.

And in the even that the diagnosis is wrong, the rest of us will still
have the complete picture of what happened from dmesg, rather than seeing
random kernel errors (from other code) happen later without knowing there
was some kind of BIOS or hardware fault that triggered it.

Having them all in one place is rather useful.
And you can still configure rsyslogd to _also_ send the BIOS/hardware
errors to a separate destination, if that turns out to be useful.

Cheers
