As I understand it, this converts the output back to the 'old style'.

That may be because it doesn't need to scan the PCI bus in single head
mode.  Don't know enough about XFree86 to comment.

I don't have the hardware so I can't say if this is a valid BusID but it
seems a little sus to me.  I could be wrong.

Isn't this still a 'new style' address, the things you aren't producing
any more.  Might this be (a|the) problem.

Slightly more tangentially, have you tried on a 2.4 series kernel or
tried X.org?  That might give you some intuition into whether it's
possible and what other problems there might be.
