I hope not. To be honest, I can't imagine them doing that.

I did have a power plug converter for US -> EU power sockets, but it was
apparently made by people who never actually seen an EU power socket since
it didn't fit. So I need to get myself a proper converter first before I
can try and test 2.6.30 on it :-(
