You are mistaken.

You can have 3.3V 16bit cards.  They are keyed the same way that 3.3V
CardBus cards are keyed, but lack the attracive copper dimples.

I have several 3.3V 16-bit cards in my pccard collection.

The real issue with CardBus is that the 32-bit bus requires a special
CardBus bridge.  The Libretto L50 has only a PCMCIA bridge, which only
supports the 16-bit cards.  If you file down the 3.3V 16-bit cards,
they will work in a Libretto 70 (and I'm pretty sure a 50 too).
