Did you try without the USB mouse ? And also without compiling the
USB OHCI driver in the kernel at all ?

If I understand you properly, it hangs before going to sleep (you don't
get the blinking sleep light). So we should be able to track it down.
Is the display backlight turned off when it hangs or is the screen still
powered down ?

One thing we can try is:

 - get the latest rsync
 - enable xmon in your .config
 - edit drivers/macintosh/via-pmu.c, in function broadcast_sleep(),
   line 1565, just before:
   ret = notifier->notifier_call(...)
   add :
   xmon_printf("calling notifier %x\n", notifier);
   and after the call :
   xmon_printf("return notifier %x\n", notifier);
 - edit drivers/video/aty128fb.c, comment out the call to
   pmu_register_sleep_notifier() line 1907, and add
   a "return;" at the beginning of aty128fbcon_blank() (line 2279)
   so that the function does nothing.

Now, compile the kernel, go to sleep in console mode, and tell me
about the latest message you see before it dies. Also backup the
System.map of this kernel as the values displayed by xmon_printf will
have to be looked up there.
