I don't think that sed/sh is the answer.  I'd use Perl.  Basically you
can write a smart regex to detect an equal sign followed by a hex code. 
The regex should capture the hex code.  From the trapped code, you could
use the chr() function to replace the value (0x0a = newline):

[root at lite src]# cat test.pl
#!/usr/bin/perl

print "==" . chr(0x0a) . "--\n";

[root at lite src]# perl test.pl
==
