I have an Acer Extensa 390 with TI 1250 cardbus bridges, which normally
runs 3.2-PAO. I had tried 4.0 earlier without much success, and decided
to give it a whirl after this change. Unfortunately, not much success
this time either. I get the following crash while booting - I have no
idea whether this is related to your changes or not:

Looking at the code in pccard_card_attach(), since it never gets to
DEVPRINTF((dev, "chip_socket_enable\n"));
I assume it crashes at this line:
