I cvsup'ed, and see no improvement with the Linksys card (it is still
probed and attached twice, resulting in a hang).

With a WaveLAN Gold card (also probed twice), however, the second
attachment fails ("wi1: init failed", "wi1: mac read failed 5",
"device_probe_and_attach: wi1 attach returned 5") and the machine
survives the card insertion. However, upon removal, it panics in
wi_intr+0x38.

I have some more cards I could plug in, in case that'd help. Let me
know.

This is with these pcic sysctls set (all defaults):
        hw.pcic.irq: 0
        hw.pcic.ignore_function_1: 0
        hw.pcic.intr_path: 2
        hw.pcic.init_routing: 0
        machdep.pccard.pcic_resume_reset: 1

Since it seems to work for you, Randy, maybe you could email me you
kernel config file and sysctl settings, so I can check if they work for
me as well?

Warner, feel free to make me run patches and test things; anything to
make this work :-)

Lars
