APM suspend/restore doesn't save IDE disk settings ?

Hi,

with Linux 2.0.32 compiled with full APM support using

# hdparm -m 16 -c 1 -W 1 -u 1 /dev/hda

I get

# hdparm -tT /dev/hda
/dev/hda:
Timing buffer-cache reads: 32 MB in 1.20 seconds =26.67 MB/sec
Timing buffered disk reads: 16 MB in 3.57 seconds = 4.48 MB/sec

but after suspending and resuming the notebook I only get

# hdparm -tT /dev/hda
/dev/hda:
Timing buffer-cache reads: 32 MB in 1.20 seconds =26.67 MB/sec
Timing buffered disk reads: 16 MB in 4.93 seconds = 3.25 MB/sec

and I have to run hdparm -m 16 -c 1 -W 1 -u 1 /dev/hda again
to get the original performace.

is this correct behaviour ?
is it possible to run a shell script after APM resume (without PCMCIA devices) ?
