It sounds like its rebooting before it even starts the domain 0 kernel,
so its rather surprising that the kernel version makes a difference.
Perhaps the kernel size has something to do with it?

Are you sure you're capturing all the boot messages? have you got a
serial line attached?

How much memory has your x205 got? I'm wandering whether something is
going disasterously wrong with the e820 parsing. I still can't see why
2.4 vs 2.6 should make any difference. Are you sure you're not using
different Xen versions in the two cases?
