The modprobes in the posted dmesg were done manually by me to see if
it would help. It didn't.
As for Ubuntu doing it, I don't know. Any way I could tell? I've
looked into /usr/lib/pm-utils/pm-functions and the $SUSPEND_MODULES
variable is set to empty, so it doesn't look like it's doing it for
any modules at this point.

Is there something I can try?
