I just tested on my Lenovo T61 laptop (fc16, x86_64, 3.2.x + rt, 
alsa-tools 1.0.25). I was able to test both with a PCMCIA card and a 
PCIexpress card (plus a Multiface II) - the laptop has both types of slots.

PCMCIA: the kernel claims no IO box was connected but the firmware 
somehow loads anyway and the card appears as an ALSA device in 
/proc/asound/cards. Hdspmixer starts, but has a "HWdep ioctl failed. 
Metering stopped" error and the meters do not work. It does initialize 
the mixer matrix properly and I get sound out the headphones.

PCIexpress: the kernel finds the IO box and loads the firmware, 
hdspmixer runs and the meters work. I get sound out of the headphones.

In both cases audio works fine, I get no xruns and jack does not hang 
(sorry, can't reproduce your problem).

Anyway, there is something fishy because the behavior is different for 
the two slot cards. Same kernel, same everything, the only difference is 
where the card is plugged in. Very weird.
