There is included support for ext2 but as a module. There is currently 
no reason to have it directly in kernel wasting RAM for 99% of people.

Yes. However the one for latest firmware is not released yet. SDHC 
definitely needs to be in kernel but when enabling additional features 
already present in kernel (ext2) consider using modules if you plan to 
publish such kernels. It is not fun to see tons of precompiled kernels 
floating on the net with various random bits enabled. Poor user who need 
two such features from different kernels :-)

No need to have it directly in kernel. It is not too hard to 'insmod' it 
if you need it, modules are in /mnt/initfs/lib/modules/<kernel version>

If you use the bootmenu [1], it can even insmod it for you (even if you 
boot from internal flash) if you add it to bootmenu.conf file.

I did not notice any slowdown (exept maybe the metalayer-crawler on 
boot). I did notice better stability and improved interface. 2007 on 770 
is my primary system now.

As for the kernel thing in your question, well, it is not kernel, kernel 
is exactly the same one as in IT2006 (which is good since you can 
dualboot between 2007 and 2006).


BTW, subject named "Help" is asking to be ignored :-)
