Hmm... That's definetly not normal. Seems like something is causing excessive current consumption. The current consumption of Virus is so minimal that it really sohuldn't cause heat dissipation problems. I think it would be wise to check that the transformer is suitable for the unit (the rack unit has an external transformer, right?) and if it's ok then check the groundings. If the regulator is hot it's only a matter of time when it gets burned.

You right the consumption come from the display module, this one have two integrated circuits built in so I dont have other option, just locate the LM7805 in better place and enjoy the Virus for while.
