Screenshot of ICS 4.0.3 version information on ODROID-7.

Here is a brief instruction how to port/install the ICS into ODROID-7.
Note, this is a very early version. Unstable and there are many unsupported features.

1. Get the Kernel source code of ODROID-7 (ver 2.6.35)
http://com.odroid.com/sigong/nf_file_board/nfile_board_view.php?keyword=&bid=41

Modify the touch screen driver as below.
kernel/drivers/input/touchscreen/odroid7_MT_touch_portrait.c

169                 input_sync(hkc1xx_touch.driver);
170 
171 //codewalker
172                 input_mt_sync(hkc1xx_touch.driver);
173 
174                 input_sync(hkc1xx_touch.driver);
175 
176 
177 #if defined(DEBUG_HKC1XX_TOUCH_MSG) 
178 printk("%s : Penup event send[x = %d, y = %d]n", __FUNCTION__, hkc1xx_touch.x, hkc1xx_touch.y); 
179 #endif

2. Download GPU device driver source code of Nexus-S from this link.
https://github.com/Kwiboo/kernel_samsung_crespo/tree/master/drivers/gpu
Copy(overwrite) the GPU code to ODROID-7 kernel source and compile it.

3. Get the official Android ICS source code.(android-4.0.3_r1 IML74K)
repo init -u https://android.googlesource.com/platform/manifest -b android-4.0.3_r1
repo sync

4. Get the modified files from below link and overwrite it into /device & /vendor directory of ICS source tree.
http://dl.dropbox.com/u/4485660/ICS.tar.gz
This file contains various patches.

5. Modify WiFi code as below for internet access.

device/hardkernel/odroid7/BoardConfigCommon.mk

71 #WIFI_DRIVER_MODULE_ARG := "firmware_path=/vendor/firmware/fw_bcm4329.bin nvram_path=/vendor/firmware/nvram_net.txt iface_name=wlan" 
72 WIFI_DRIVER_MODULE_ARG := "iface_name=wlan firmware_path=/vendor/firmware/fw_bcm4329.bin nvram_path=/vendor/firmware/nvram" 

And copy the fw_bcm4329.bin & nvram into proper location.
Modify hardware/libhardware_legacy/wifi/wifi.c
