This is pretty ugly, but doesn't require any changes to the source code:

concat (
suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware, 1, 1))),2),
suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware, 2, 1))),2),
suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware, 3, 1))),2),
suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware, 4, 1))),2),
suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware, 5, 1))),2),
suffix (concat ("0", binary-to-ascii (16, 8, "", substring(hardware, 6, 1))),2)
);

Basically gets each char, sticks a 0 on the front, then takes the last
two chars, then concatenates the whole thing.
