No it has to do with the SD clock.

quoting solution:

Works for me. Two shell scripts:

/etc/apm/suspend.d/00sd_idleclk
which contains

============================================================================
#!/bin/sh

echo 1 > /sys/module/glamo_mci/parameters/sd_idleclk

touch /home/root/.profile
sync;sync;sync
============================================================================

and
/etc/apm/resume.d/00sd_idleclk
which contains

============================================================================
#!/bin/sh

echo 0 > /sys/module/glamo_mci/parameters/sd_idleclk
============================================================================

with that, suspend and resume works as expected.
