No.  It was actually a pain in the neck, because it got in the way of
the boring Linux software RAID I was using on the machines.

OK, now I find it terribly odd as well.  This was definitely a problem
though, with one machine detecting the standard software RAID as well as
the VIA raid, built from device mapper components.

Which was well before we had connected the machine to the Internet, so I
don't expect it to have had any chance to download anything more.

Er, but if you tell me that this isn't supported then I don't doubt you.

Well, now I am as puzzled as heck about this, because the problem
definitely resembled FakeRAID detection -- but, I guess, that must have
been something else.  

Now I *really* want to know what it was, because I was happy that I
understood the cause of the problem before, and now I don't. :/
