Hi,
I suppose you are using CBQ ? You can create more classes to achieve it.

Gives :
cbq qdisc
\ bounded class rate = 2Mbps
\ bounded class rate = 256 Kbps
| \ class rate = 64Kbps
\ other class rate = 512 Kbps
\ other class rate = 512 Kbps
\ other class rate = 512 Kbps
\ ...
But I think it will not the give the results where you are looking for.
Or use htb :)
Htb has a ceil parameter to ceil a class so it does exactly what you want.
With rate you can specify the minimum rate and with ceil the maximum rate.
