He writes all the pccard and cardbus support and has an amazing collection
of pccard's that he uses for testing.

No, incorrect.  I'm sending this e-mail over a 16-bit wavelan pccard
using NEWCARD.  What that means is that older pccard _bridges_ that
are only ISA (not PCI devices) are not supported by NEWCARD but are
supported by OLDCARD.  If your bridge supports cardbus cards then
NEWCARD will work with it just fine.
