Are you sure that is true for 600 (Uniglide)?
BTW, if it is Uniglide, Efelty's cassette won't fit the new wheel. The last cog no longer holds the other cogs and spacers on in the modern system; there is a separate lockring (which adds width, which makes me suspect that it is possible to have an 8-speed, Uniglide, 126mm wide hub.)
Incidentally, I've never tried it but it always looked to me like they were being too conservative with the clearance on 130mm road wheels and the wheels would work if you had someone remove 2mm of spacers from the left, and install a 1mm narrower locknut on the right, along with leaving out the 1mm spacer. Maybe if you could flex the frame a lot by pedaling, or you ran a 15t smallest cog, there'd be an issue, but to me it sure looks like there's room for a modern hub to fit in a 126mm frame.
