OK, first of all, there's obviously a bug somewhere.
But the machine not powering off is no big deal. Once it halts you
simply turn it off. But losing hyperthreading is obviously not good.

Well, you could try using APM instead of ACPI, if your BIOS supports it.
That might get you an automated power-off. But probably not
hyperthreading. Probably not worth it.
But there are newer kernels in Sid that you can try, such as
linux-image-2.6.32-2-vserver-amd64 and linux-image-2.6.32-3-vserver-amd64.
