regex is your friend. In perl

while (<>) {
chop();
$cpu = $2 if (/^cpu( family)?\s*:\s*(\S*)/i);
$model = $1 if (/^model\s*:\s*(\S*)/i);
$model_name = $1 if (/^model name\s*:\s*(\S*)/i);
$bogomips += $1 if (/^bogomips\s*:\s*(\S*)/i);
}

$cpu = $model_name if($model_name);
print "cpu=$cpu\n";
print "bogomips=$bogomips\n";

Converting to regexec for C is left as an exercise for the reader :).
