Hmm, no real idea here. Try I different kernel, I'd say :-\
Or try fiddling with hdparm parameters.
Maybe you already did that, and one of these parameters conflicts with
suspend due to the device forgetting the setup, but the kernel
remembering it ? I had this happen to me several times...

Try to use strace -f in order to diagnose this problem upon pcmcia startup.
If it complains about "Permission denied", then it probably has a reason...
