and as luck would have it, I have a Lenovo that shows the same SD card used in my Alienware as a USB disk :)

Here's syslog from when I inserted the SD card:

That last line is probably from me screwing the filesystem by doing strange partitioning on it from time to time for other testing.

So here's udisks from my Lenovo:

Not specifically on this machine that, like Haggai's media: and compat: are empty, interface says usb.  But unlike his, drive vendor is Generic, drive model is Multi-Card. His said drive vendor Single, drive model Flash Reader.  Same for the by-id field, which just reflects the drive vendor and drive model fields :(

That means we can't rely on those fields to provide reliable data, they are apparently OEM fill-in fields.
