Load module rescheduling

Tried to match the actual PSP at least a bit, and but went on the lower end for delays rather than higher since most games are working already.

Should fix Sol Trigger and fixes the Tales of the Heroes: Twin Brave demos for me.

Possibly may help #887, not really sure...

Tested on a number of other games and none of them broke.

I'm trying to decide on if a more general solution is needed.  I think the IO funcs do this (and maybe that's ultimately why these do, really...), but they have more to them as well...
