I'm having similar problems here (on a ThinkPad T42p).
I'm loading if_ath and if_em at boot time, and when I plug in my ath0
cardbus card, the kernel panics with a NULL pointer dereference similar
to yours.
If I don't load if_em, or don't plug in the Atheros card, everything
seems to work fine.
Looks to me like a problem with interrupt sharing, since both cbb0 and
em0 are getting attached to irq4.
regards,
