Wouldn't it be cool if you met this Dwemer during your travels in Skyrim? Maybe Yagrum's search has sent him to Skyrim, still searching aimlessly for his lost people?
He's probably dead (and most likely still where he was in Morrowind, how could he possibly travel in his condition!? Did Divayth Fyr save him?) but it would be cool if we got to meet him in Skryim, with his mechanical legs and everything
Is he even alive? Altough his Corprius disease makes him immortal doesn't it?

The book "The Infernal City" is based on events in Morrowind following what occurs in the game Oblivion and before the game that is Skyrim. In it, it describes how the hovering moonlet over Vivec city finally falls and crashes into the continent, a super-eruption of Red Mountain, and an invasion by Black Marsh Argonians. Basically, most of Morrowind is reduced to a wasteland. As such, since Skyrim is a neighboring nation to Morrowind, I'm expecting a heightened Dwemer influence in Skyrim from its influx of refugees, particularly in its eastern regions.
Divayth Fyr was a Telvanni, who, as I remember, was working on a cure for corprus disease, which Yagrum was inflicted with. The reborn Neraverine was his first successful cure. I suspect a cure from corprus would also reverse its immortality side-effect. Keep in mind, it's probably about 240 or so years between Morrowind and Skyrim. Also given the geologic and political events in that span of time, Yagrum or Divayth Fyr's survival odds are rather low. You never know, however. Divayth was a powerful wizard, after all.
