Somewhat similar vein, but a different set of symptoms, I've seen a
RedHat box not see that the CF card changed...
(USB SanDisk CF & SD reader, also using only CF cards.)

insert 128MB CF card.
everything is ok.
remove 128MB CF card, still see 128MB partition
insert 256MB CF card.
see 128MB partition.
(based on /proc/partitions)

I've not followed this up to figure out why yet.
You might check that situation to see if yours is related at all.
