Currently doesn't work is wifi, camera, and there are many known bugs:
-Wiping data delete the gsm radio. The /system is too little to have everything, so the ril is in /data.
-Android won't detect SD card if there is an ext2 on it. It tries to mount it as vfat instead of mounting the correct one.
-Black/white lines appearing somehow randomly.
-No tethering works currently.
-This is unsigned
-Headset detection works, but isn't shown in notification panel.
-No AGPS, so getting a GPS fix can be slow.
