In addition to the other answers you might want to verify that the 
resulting OSKit really is built correctly.
When calling configure on the OSKit you must ensure that

   --enable-indirect-osenv


is present. That was missing from your "OSKit compilation and 
installation and PCMCI support" email, sent earlier to this list.
That option is present in the debian/rules file and is definately needed 
for Linux drivers trying to read BIOS configuration data in the lower 
address spectrum. Addresses that otherwise trigger "page zero" trapping. 
It might not be lacking from your build but pointing it out might help 
someone else with similar problems.
