Alright, I've been looking at the code some more, and I found this:
/* The IBM TP600E is gracious enough to pre-allocate a memory
* space for the PCI-CardBus bridge, so all we need to do is map
* it in, and save the address in the softc register */
rid=PCIR_CARDBUS_BASE_2;
sc->cb_base_res=bus_alloc_resource(dev, SYS_RES_MEMORY, &rid,
0,~0,1, RF_ACTIVE);
Basically this looks to me like you're assuming that all laptops
pre-allocate a memory space for the pci-cardbus bridge... and that's why
my laptop can't map the register space... because it's not pre-allocating
memory for the bridge. I'm looking into how to do this, and when I am
done, I'll make patchs to your patchs :-) for those of us who got this
ethernet card with their Dell Inspiron 3800's :)
