Actually it's for the machines with psycho's (not sabre's), so it's for
the UltraSPARC Engine ATX (which is distinct from the AXi) and the u30.
The u10 is built around sabre, isn't it?

I've been trying to track down the 'uncorrectable DMA error' problem
in OpenBSD for awhile now, with little success.  It appears that the dma
unit is requesting transfers of invalid addresses (ones not in the iommu,
which is why the PA is -1), but I have not tracked down the cause.
