First, thanks $aur0n for the nice work and I can now also boot from SD card and enjoy the rooted system in EXT4 
For those interested in overclock, you can try this kernel (I have tested it in Archos 70IT, but it should work in A101/A43IT as well):
** See below for instructions on how to apply this overclock kernel with the newest firmware 2.1.0X
2011-02-01 (Newest)
===================
– Rebase from the original kernel source
– Complier optimization
– Add interactive CPU governor
– Bluetooth fix (please test, should still have problems)
– For those enjoying online flash movie, e.g. myTV.tvb.com, please set the freq to min:1000/max:1000 (Best with flash player v10.1.105.6 or upper)
– Set freq to min:1100/max:1100 for best 3D gaming experience

Get rooted with newest firmware 2.1.0X + overclock!
** Special thanks to chulri for the updated initramfs **
0) Install SDE first
1A) For firmware 2.0.12, download the newest initramfs from here: http://code.google.com/p/archos-gen8…2_temproot.zip
1B) For firmware 2.0.13, download the newest initramfs from here: http://code.google.com/p/archos-gen8…03_tmproot.zip
1C) For firmware 2.0.14, download the newest initramfs from here: http://code.google.com/p/archos-gen8…04_tmproot.zip
2) Grap the newest overclock kernel from the links above in this post
3) Reboot your Archos holding "Volume -"
4) Recovery System -> Developer Edition Menu -> Flash Kernel and Initramfs
5) Connect USB and copy initramfs from (avos_2.1.02_temproot.zip) and copy zImage from (zImage_archos_1200_ext4_fix07.zip or 1280’s kernel) to Archos machine
6) Reboot by holding "Volume -"
7) Choose the 2nd menu item (Developer Edition)
8) Here, you get rooted in the newest firmware + overclock kernel
9) Enjoy ^_^

==================
– Not guarantee to work with $aur0n’s 0.4.1 initramfs. Please use 0.2/0.3 initramfs (boot from SD) if you get problems
– More stable & smooth
– Overclock to 1280Mhz (Stable in playing NFS shift for a few hours – I am in world track now…)
– Remove 250Mhz and add 600Mhz (as 600Mhz is needed for SetCPU to display correctly)
– Fix the SetCPU ‘time in state’ problem
– Revert the bluetooth driver
– Cherry-pick more commits (refer to my github)
– Special thanks to $aur0n’s initramfs

Beware! After overclock, you will feel a bit hotter than before and battery drains much faster!! Flash it at your own risk.
What you need to do is:
1) Install SDE
2) Get the initramfs from this post (download the kernel+init.zip and extract it): http://forum.xda-developers.com/show…44&postcount=1
3) Replace the zImage with the new overclocked kernel
4) Boot into SDE recovery menu and copy the initramfs.cpio.gz and zImage through USB cable
5) Boot into SDE developer OS
6) You should get all your apps here and have superuser right now
You will now have read/write access to /system/ or /data/ …etc.
Next step: You can download GScript from the market (free) to make some custom scripts to remove unnecessary apps and replace the hosts file, etc.

Give us a "Thank" if you think this kernel works great for you

c’est tres bon !
mais faites attention à l’augmentation de la CPU
