"he would use the CF->pcmcia adapter do get more space between the 2 cards so he could use it like that:
pcmcia-jacket -> pcmcia-cf-adapter cf-pcmcia-adapter -> pcmcia GPS card and a wlan card directly in the jacket. "

Exactly. I have the 'dual PCMCIA sleeve', primarily because I wanted the extra battery power to drive a Cisco WLAN card (100 mW) for longer periods.

With an extended PCMCIA->CF adapter or by stacking adapters, it should be possible to get the antenna of the second card to clear the other antenna, and put the two cards together into the dual PCMCIA sleeve.
