Ah, silly me, I set IOMMU_DEBUG to Y at some point without realizing.
Taking that away removed the issues and I now only get:
[ 0.000000] Checking aperture...
[ 0.000000] CPU 0: aperture @ 4000000 size 32 MB
[ 0.000000] Aperture from northbridge cpu 0 too small (32 MB)
[ 0.000000] No AGP bridge found
...
[ 47.737770] PCI-DMA: Disabling IOMMU.
Which makes a lot more sense.
Sorry for the noise.
Thanks,
Nish
