does one always need to write a WDM driver?

Hello

I was trying to figure out if there was any need to (and if one could) write a WDM driver for a PCMCIA based GPRS card, the microsoft site mentions at
http://www.microsoft.com/whdc/archive/wdmoverview.mspx

that WDM enabled developers to write one drivers for multiple platforms, so that in case you havem ultiple GPRS cards being developed with different capabilities (which would constitue a platform ?) yone would go for WDM driver development, correct?



also on the same site it mentions that WDM drivers can be written for thefollwoing WDM bus
WDM Bus and Device Support

Bus Support. In the context of WDM, a bus is any device to which other physical, logical, or virtual devices are attached. Windows XP contains WDM support for these buses:
? PCI
? Dynamic Plug and Play serial I/O buses, including USB and IEEE 1394
? SCSI
? NDIS
? Remote NDIS (RNDIS)

PMCIA or PC card is not mentioned, is that the case, or is PC Card a special case of PCI?
