Yes - even though I have reservations about patch (5) and the
problem is related to a complete lack of programming model for
these host controllers and a clear separation between what's
done in the OS vs bootloader, PERST handling in this host
bridge is *really* a mess.

I applied 1-9 to pci/aardvark.
