Currently we only build kernels for i386 and x86_64, but ploop code 
should not be arch-specific (unlike, say, checkpoint/restore stuff), so 
it makes sense to try building it for other arches as well. We have 
plans to merge the ploop kernel code upstream (in one way or another).

Fixed in git:
http://git-ovzcore.sw.ru/?p=ploop;a=commit;h=282a186b7

Although I don't currently have a way to test it.
