It seems like the last non-drive by changes to it > are from 2010 and I'm not sure how common these systems were. 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?
