You should be able to use the config for another kernel, as long as the config 
is for the same base-level kernel (e.g. it may not work to use a 2.6.18 config 
to build a 2.6.20 kernel, and probably even worse the other way around).

As stated in a post yesterday, the best way to achieve this is to wait for one 
of the distributors to do the hard work of figuring out how to adopt the kernel 
patches from Xen into the next version of the kernel - because that's what 
you'll have to do. 

However, if you want to go with the current FC6 Dom0 kernel, and use the new 
3.1 tools and Xen Hypervisor, that should work ok.
