These systems were plentiful for 2-4 years after the original series
made it in. After that, the Intel and AMD IOMMUs should were shipped
and were superior to this chip. So, even in systems where these might
be present, the AMD/Intel ones should be used (unknown if they were
shipped on the same ones, as both Muli and I have left IBM).

You thinking about removing the code?
