I don't have an EISA system with the new EISA conf code, but I think that the EISA probe is quiet unless a controller is found. You might try booting with verbose (-v). Have you disabled uha in user config? This has been known to conflict with the 274x/7770 causing them not to be probed. At boot go into to user config (-c) and try disabling uha0.
