I do not think that you can create an emulator with version 2.3.6, but you can do it with version 2.3.3 and a screen size of 800 * 600.
go to AVD Manager> Create ... and fill out the screen as follows:
Name: galaxyNote
Target: Android 2.3.3 - API Level 10
SD Card: 256 MiB
Leather: 800 * 1280
then click on create AVD. done.
