Installing CWM Recovery
CWM Recovery for the Thinkpad Tablet can be found on XDA. You need root on your Tablet to install CWM Recovery. Download the recovery image (recovery.img) and follow the instructions provided by the post. It basically comes down to pushing the image file on the sdcard and overwriting the boot partition.
Push the recovery image to the sdcard
adb push recovery.img /mnt/sdcard/

Get root
adb shell
su

Remount /system and backup install-recovery.sh (optional)
mount -o rw,remount /system
mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.backup

Overwrite the boot partition
dd if=/mnt/sdcard/recovery.img of=/dev/block/mmcblk0p1

Entering/Booting CWM Recovery on the Thinkpad Tablet

Shut down your Thinkpad Tablet
Press the power button until the Tablet vibrates
Keep pressing and releasing the volume up button until you see Booting Recovery Kernel Image in the upper left corner. It's all about timing of when the volume up button is pressed. That's why it's a good idea to just keep on pressing and releasing the button until the message appears.
