It's my belief that this could be accomplished with hijack. I went through a bit of an explanation on how this would be done over in the Programming forum earlier this evening... Basically, the player gets its status (including standby mode and whether it's paused or playing) from the flash. The kernel can give the player phony state data at any time and the player won't be the wiser. So on bootup, Hijack could in theory supply certain values from config.ini instead of the ones from the real flash block. In your case, you would want to define either pause or standby in your config.ini and then hijack would pass that along when booting up. The only caveat would be you want it to only happen on AC power, but since Hijack knows what power source it's on, that shouldn't be a big deal.
