I would also recommend the brilliant book by Cameron and Trivedi http://www.stata-press.com/books/mus.html,
chap. 4.6.1, for your attention where they -simulate- the effects on the OLS estimator if the errors are really chi2 distributed...

Hmmm, your message is a little short of substance, but still: the normal thing to do is to inspect the residuals for normality, not the covariates.

thanks
