BIOS Update? You probably mean system update (and the latest is 710031 :)

There is a workaround for that, see below.

Er, this actually doesn't mean anything.
Linear stores and ATA stores arithmetic are very different (because
their structure is different). This difference you experience can
come from a problem on the ATA store or not.
Indeed, on ATA stores, when it says X KB free, it means 2 * X 512
sectors entirely empty. It doesn't count partially free sectors,
although the store can use it. The reason is that ATA Support doesn't
reserve sectors for transaction purposes but uses any free sector
(well, actually, the closest free sector) to save time with spinning
devices (not sure this is pertinent) but also to not use always the
same sectors which, with flash technology, would be bad for them
(nevertheless, the map is always at the same place, but it can be
moved if the sectors it is on appear to be dead).
So if I just indicate the sum of all available byte in sectors, the
result is much larger, but you can have a store full error (because
there is no free sector left) while memory infos tends to prove the
contrary.
Of course, ATA Support can use the free bytes here and there.
Nevertheless, there is of course a problem and, as you think, it's
very probably there (and it also explains the abnormally high value
of used memory).

Here, I got without any problem the infos on my 16 MB CF card, but it
still said 2.4 MB used.

Well, it's not already written in the documentation.
Having the system prefs open (only) -> erases the stores which are
mounted. This applies actually via the system mechanism and it works
when you mount a store (either automounted stores when inserting a
card or manually mounted stores).
Having the ATA Support prefs open -> do not auto mount stores.

Thanks for the full report. This helps. And since I have a problem
when doing the same steps (although not exactly yours, but it's very
probably linked), I think I'll be able to fix it. If I'm less tired
than I have been these last days (yes, that's why the project doesn't
advance), it should be fixed for next release.
Thanks again.

Paul
