Kernel 2.6.3

[Harry G]

I am considering installing the 2.6.3 kernel on my system, a Libranet
2.8.1 box.  (xfs, the file system,is not supported in the stock kernel)
A couple of basic questions, if you do not mind.

1.  Are there any basic issues with this kernel?

2.  I use Grub.  It will just append to my /boot/grub/menu.lst, right? 
I don't want to loose the stock boot option.  I am downloading the full
kernel, not a patch.

3.  Where can I find good documentation on installing this?  I tried to
do one via the Libranet Adminmenu, but it didn't work correctly, so I
would like to do it the old fashioned way.

Thanks for your patience.
