Patch that breaks Cardbus support on HP zv5460us laptop

Hi All,

Using git-bisect I found the patch that breaks cardbus support on my
HP zv5460 laptop. This was applied between 2.6.14-rc2 and -rc3;
reversing the patch on 2.6.17.7 makes Cardbus work where it formerly
did not. sha1sum of the patch is:

12f44f46bc9c6dc79255e661b085797af395d8da

I have attached lspci -vvv output; please ask if you need more info.
(lspci output is with Cardbus card inserted.)

-Chris
