[c-nsp] VLAN ID limit?

For some reason, my Catalyst 2900 series (WS-C2924-XL) does not like 
VLAN IDs higher than 1005:


sw01(config)#switchport trunk allowed vlan add 1202
Command rejected: Bad VLAN list - character #5 (EOL) delimits a VLAN
number (1202) out of the range 1 to 1005.

This is with a trunking interface:

interface FastEthernet0/1
  duplex full
  speed 100
  switchport trunk encapsulation dot1q
  switchport trunk allowed vlan 1,3,100,1002-1005
  switchport mode trunk

IOS is 12.0(5)WC8 (C2900XL-C3H2S-M).

I'm pretty sure this has already been asked a thousand times, but how do 
I get around this issue so I can get support for the extended VLAN IDs 
up to 4096?
