Are they all "_x"?  You could do something like:

for i in *_x.*; do mv -f $i `echo $i | sed -e 's/_x././'`; done

it would be more flexible to do in perl of course:

opendir(T,".") || die "can't open dir:$!";
	next unless ( -f $_ );
	($a,$b) = /^(.+)\.(.+)$/;
	next unless ( $a && $b );
	$a =~ s/..$//;

Warning: none of these have been tested, I just wrote them out so YMMV.
