On  2011-04-16 I filed a pretty similar bug report in Red Hat bugzilla.
It sits here: https://bugzilla.redhat.com/show_bug.cgi?id=697150
still as ASSIGNED.  A kernel was based on 2.6.35 running on Asus K52Jc
but the problem really looks the same.  Assorted additional information
is attached to that bugzilla entry.  There is also
https://bugzilla.redhat.com/show_bug.cgi?id=675564

After all modifications described in my report, which included adding a line
SUSPEND_MODULES="xhci_hcd sdhci_pci sdhci"
in /etc/pm/config.d/hci.cfg I never had suspend/hibernate issues
again.  As a matter of fact I forgot about the problem. :-)
