this is the problem of the timing of initialization.
i've not noticed this problem because i worked mainly on vx222 at the 
time to write the firmware loader.

a pcmcia PCCard module on linux is initialized indirectly by the card
manager after the module is loaded.  before that, the module is not
initialized properly, i.e. no i/o resources are assigned, so calling
vxloader via post-install fails.

i believe there must be a good solution for the automatic loading.
i'll check that later.

i found it, too, and did a quick fix in the train returning from the
LAD meeting last evening :)  please try the cvs version.
