How to get around this....

If you can't get around it by not starting anything (by default) on AC power (that is, using, hijack to launch "occasional use" things), I'd recomend just commenting out the offending ;@EXECs and rebooting before syncing.

Really, though, if we disregard launcher because that functionality will be in hijack shortly, there are extremely few situations where one really needs to have an app start on an AC boot.
