A fun challenge for those of you who eat raw upstream kernels
for lunch:

1) Untar an upstream (say 2.6.30) kernel.org kernel
2) From the bash command line ONLY, execute one or more
   commands to configure the kernel so "make" will build
   a fully xen-ified kernel.  (Everything else can
   use the defconfig default.)

For extra credit:
3) Determine the shortest sequence of commands to do
   the above.

After many tries, I have not been able to do (2) at all.
I always have to fall back to an existing .config file
that was created using menuconfig.  (I *suspect* this is
because PARAVIRT_GUEST is defined in Kconfig using a
menuconfig line rather than a config line, but am unsure.)
