I use something similar and use ceil 286kbit while synced at 288kbit without problems. If your modem is connected by eth rather than ppp then htb/whatever will see the packet size as ip len + 14 - so you need to account for that. I think that produces a corner case (overhead < 14) where you would need to put in a negative number - I don't think that will work, but haven't tried.
