Why wouldn't it affect Chrome if the Root CA is trusted by Chrome? According to http://www.chromium.org/Home/chromium-security/root-ca-polic... they use the underlying OS list except in the case of Linux in which they use Mozilla's list.
"In addition in Chromium 13, only a very small subset of CAs have the authority to vouch for Gmail (and the Google Accounts login page). This can protect against recent incidents where a CA has its authority abused, and generally protects against the proliferation of signing authority."
(disclaimer: I work for Chrome but not on these features.)
