Depends on if the actual >pinout is differant on a cardbus and 16 bit slot. But as far as I know >it isn't since the pcmcia revisions have all been in software since >about 2.0 The pinouts are not only different, but they're selected by the driver chip depending which system is required. The data/address bus stuff isn't (e.g.) multiplexed onto the same pins, it uses different pins in different positions. Without the hardware, you're stuffed. And, strictly, a Cardbus card shouldn't even *fit* into a PCMCIA 16-bit slot. There main problem with USB cards seems to be that the maximum data rate is too low on the sixteen bit systems. According to the PCMCIA-CS howto, the maximum rate is only about 2-3Mb/s, irrespective of the hardware.
