It's there to enable some kind of serial console before PCI probing
and device mapping has been done, the address is arbitrary.
Maybe the new mapping could remove the old one.

Strange, at least Debian 3.1 R8 (CD and direct -kernel), Debian 4.0 R5
(CD and direct -kernel), Debian 4.0 R6 and Gentoo 2008.0 act like
before.
What kind of setup do you have? At least OpenBIOS config is not
standard, you have enabled PCI debugging.
