Yes.
2.6.28-ARCH + your patch fixes oops.
Cards still does not work though.

If I additionally apply Tim's patch, I get (coldplugged)
NULL pointer dereference at 0000000000000140

IP: snd_hdsp_interrupt + 0x9c/0x220

Trace:

handle_IRQ_event
handle_fasteoi_irq
do_IRQ
ret_from_intr
flat_send_IPI_mask
mwait_idle
cpu_idle


Hotplugging just disables the card (as "usual").
