A lot more x60s than ibm is shifting, certainly a lot of publicity in retrospect for what is a ready made version of what you could assemble yourself before.
Sales or no sales, it does generate publicity for what used to be just a well made laptop of yesteryear.
I assume people will run linux|gnu on it, and it isnt really powerful enough to run any software that isnt multiarch already, so all the more reason to think the buyers dont care as much about what variety the architecture is. I imagine they are the people who have power, mips and arm setups already.
A lot of that publicity can be translated to interest from other demographics than those who are already aware of foss gaming handhelds, and want more of the laptop features.
But as mentioned, it cant happen with powerVR drivers on the graphics.
