Patches floating around for quite some time, i386 is mainline already. 
Not fully sure about x86_64, but I think it they are merged too.  So any 
recent mainline kernel as crash kernel should do (and a separate crash 
kernel isn't needed too).
Also with the default xenheap size the crashkernel ends up at @16m, 
which is a common location for pre-relocation crash kernels, so it 
should work with older kernels just fine too.  Of course you still have 
the option to explicitly specify the location ...
cheers,
