The AGP aperture should generally be located "outside" of those spaces.
That is above RAM and in some place where no device already resides...
It can be made to overlap RAM but that isn't a good idea (that's what
happens on Macs though due to a bug in the Apple chipset).

I don't see anything related to AGP in your output... you didn't post
the lspci as root thus it's missing all the useful infos ;) Also, the
AGP base isn't generally a PCI BAR of the bridge... it is one in your
case ?
