Yes.

I'm not sure what's going on here.  I don't know what would be special
about 'df' if reading the drive works; I'm kind of surprised that 'df'
even does any IO on a mounted filesystem.  Have you tried more than
one brand of CF card?

Where have you seen these similar reports, specifically?

You can't use the pcmcia-cs drivers on this system.
