Yea!

: Warner-san, What plan do you have?
OK. Each pccard child of pcic (or other bridges that supports a 16bit
card) has a pcic_handle as its ivar. So, what needs to happen here is
that we need to get the right device, and get its ivars. I've just
committed a few changes that make sure that this is the case. Now, we
get much further than before. We get into the reading of the CIS
before we die. Looks like we/re passing a bad pointer to
bus_alloc_resource in pccard_cis_scan. Looks like a bogus cast to
struct device * of the pccard_softc. Those aren't right.
I'm working on that part of things. Any cast of softc to a struct
device is likely wrong, in case you see any in the code.
