No, there is no work around till eqmule updates MQ2 and then htw or Fry makes a new compile here.
Programming is like black magic mumbo jumbo looking stuff to me, but I think what you're thinking of had to do with EQ being up and playable with MQ2, but you can't log on, because sometimes they update the loader without doing anything else. That's where you can fall back to an older loader to get in.
