This is the problem. the OSMapMemory() function in
/usr/lib/hcfpci/modules/osspec/osresour.c is being called with
wrong dwPhysMemBase and dwMemSize values.  Maybe this is caused
by an incompatible or misconfigured compiler, or a weird PCI
device configuration (our driver works just fine for many people
with lan/modem combo devices; you are the first with such symptoms).

These values actually originally come from OSGetPCIDeviceResources()
in the same file. Perhaps you could add some printk()s to see what
that function returns..

Have you applied the ACPI patches?

What compiler are you using? (gcc -v; kgcc -v)
