Reflashing it with 1.03 will probably not fix your synch error.
Reflashing will disable displayserver, which might be a good idea-- you don't need displayserver for your trip and it's beta software which means it could theoretically be contributing to your problem (although there's no evidence of that, I'm just saying that when diagnosing trouble it's good practice to remove beta software from the equation).
If you wish to re-add the voladj kernel after re-installing 1.03, you can do that. You won't be able to turn it off, but that's actually fine for me in most cases. I've gone on long road trips with voladj activated 100 percent of the time.
