I haven't done any special hdparm settings, but after some careful
experimenting with -S (even setting it to off) there was no

I persued my suspicions about APM, though, and won big. I turned off
CONFIG_APM_DO_ENABLE and, note especially,
CONFIG_APM_CPU_IDLE. Apparently, having the kernel doing CPU Idle
calls confused my Thinkpad 570 so much that it sometimes wouldn't spin
up the HDD when leaving suspended mode.
