I have the same problem with my T23.  hwclock works normally before the
first suspend, but tends to freeze the machine after it.  I have
commented out the calls to hwclock in /etc/apm/event.d/00hwclock.  The
system clock is correct after a resume, so commenting out hwclock does
not hurt.

I also added a call to 'sync' before suspending, because ReiserFS kept
corrupting /etc/modules.conf after these hwclock crashes, and that made
the machine basically unbootable.

Another cause of post-resume crashes seems to be xscreensaver with DPMS
enabled.  After a resume I'd see the screen saver animation for a couple
of seconds and then the machine just stops.  Once this happened when I
just left the screen saver active for a long time, that's when I started
to suspect DPMS.  After I disabled DPMS support in xscreensaver options,
the crashes seem to be gone.
