It looks fine to me ... I didn't realise this was broken ...

Unfortunately, EISA support needs a per bus check for the iommu (since
WAX on some of the machines has its own IOMMU but the rest of the system
doesn't). I was going to look at introducing this abstraction, but we
never managed to get an unencumbered copy of the WAX specs to get it all
working.
Thanks for debugging this.
James
