I am currently trying to do the same thing, although I do not care about 
SMP at the moment.

For the config, I have copied the CentOS config, but then adapted it 
comparing the settings with the default xen0 config. Some things I have 
disabled from the CentOS config, because I thought they were not 
supported with xen (highmem, etc). I can send you my .config file 
off-list, but note that I have disabled most graphics/video stuff, too, 
because I wont use X here.
