T1 Controller: no channel-group option

I have an MC3810 with two T1 cards in it. One card (t1 0) allows me to
configure channel-groups just fine. The second card, however, doesn't
give me the option to setup any channel groups. I've tried two different
IOS releases (12.1 and 12.2). This used to work just fine, now all the
sudden it stopped. Any thoughts? I'll attach the relevant portions of the
config below:

System image file is "flash:mc3810-i-mz.122-1d.bin"

cisco MC3810 (MPC860) processor (revision 10.01) with 28672K/4096K bytes
of memory.
Processor board ID 14775434
PPC860 PowerQUICC, partnum 0x0000, version C01(0x0031)
Bridging software.
X.25 software, Version 3.0.0.
Primary Rate ISDN software, Version 1.1.
MC3810 SCB board (v16.B0)
1 Multiflex T1(slot 3) RJ45 interface(v02.C0)
1 Multiflex T1(slot 4) RJ45 interface(v03.A0)
1 Ethernet/IEEE 802.3 interface(s)
1 Serial network interface(s)
2 Serial(sync/async) network interface(s)
2 Channelized T1/PRI port(s)
256K bytes of non-volatile configuration memory.
8192K bytes of processor board System flash (AMD29F016)

Configuration register is 0x2102

All T1 0 config options:

R2(config-controller)#?
Controller configuration commands:
  alarm-trigger ds0 alarm aggregation
  cablelength Specify the cable length for a DS1 link
  channel-group Specify the timeslots to channel-group mapping for an
interface
  clock Specify the clock source for a DS1 link
  default Set a command to its defaults
  description Controller specific description
  ds0 ds0 commands
  ds0-group Replacement of cas-group. Configure group of timeslots
to a particular signalling type
  exit Exit from controller configuration mode
  fdl Specify the FDL standard for a DS1 data link
  framing Specify the type of Framing on a DS1 link
  help Description of the interactive help system
  linecode Specify the line encoding method for a DS1 link
  loop-detect Loopback up or down detection
  loopback Put the entire T1 line into loopback
  mode Configure the controller mode
  no Negate a command or set its defaults
  pri-group Configure the specified timeslots for PRI
  shutdown Shut down a DS1 link (send Blue Alarm)
  tdm-group Configure DS0 group for TDM

All T1 1 config options:

R2(config-controller)#?
Controller configuration commands:
  alarm-trigger ds0 alarm aggregation
  cablelength Specify the cable length for a DS1 link
  clock Specify the clock source for a DS1 link
  default Set a command to its defaults

  framing Specify the type of Framing on a DS1 link
  help Description of the interactive help system
  linecode Specify the line encoding method for a DS1 link
  loop-detect Loopback up or down detection
  loopback Put the entire T1 line into loopback
  mode Configure the controller mode
  no Negate a command or set its defaults
  pri-group Configure the specified timeslots for PRI
  shutdown Shut down a DS1 link (send Blue Alarm)
  tdm-group Configure DS0 group for TDM

Thanks in advance!
