v2 HAVE_OPTION_TABLE patch

[Myles Watson]

This patch makes several CMOS variable reads dependent on whether
there's a table to read.  Otherwise you never know what you'll get
from the factory BIOS.  There are probably more, but these are the
ones compiled into the s2895.

FYI this is a worse problem than I thought.  It happens any time you
are using fallback or failover, since HAVE_OPTION_TABLE = 0 for those
cases.  As long as the CMOS isn't corrupted that's fine, but if you're
in fallback because the CMOS checksum wasn't right...

Thanks,
