The serial sonsole itself is disabled during suspend/resume, so you have to hack the serial driver's suspend/resume routines to get any output on it at that time. :-) Anyway, if you want to put some debug printks somewhere, IMO a good place to start is in resume_device() in drivers/base/power/resume.c or in suspend_device() in drivers/base/power/suspend.c (actually, there already is one, you only need to enable it).

I compiled it into 2.6.12-rc2-mm1, and first wanted to try it with module removed etc, but 2.6.12-rc2-mm1 not even freezes after resuming, but immediately reboots! So, more to track down.
