CompactFlash (as defined by the standard) is not really a PCMCIA card. That's
why you need a simple adapter to put it into a PCMCIA slot. The CompactPCI
boards I've worked on in the past actually route one or more IDE channels
from a Super I/O to one or more CF carrier sockets instead of providing
a cable header. This approach is a lot simpler than accessing the thing
through a PCMCIA subsystem since IDE drivers are pretty braindead compared
to PCMCIA.
