That's certainly true: PCMCIA currently treats cards with no CIS as
static RAM cards.  Mostly because the issue has never really come up
for me.  I think that's a bit different from an unqualified "they do
not work very well at all".

Are linear flash cards with no CIS common?  I'm only familiar with the
Intel cards, which all seem to have a CIS.  I've never had anyone ask
about no-CIS flash card support, as far as I can remember.
