I ended up writing a module which checked the IA32_MISC_ENABLE MSR on my system.
I found that it was being set incorrectly for some logical processors. Bringing
up a DomU (prior to fixing up the pfn_info structure) on one of these processors
was the reason why the alignment check was being thrown. This was on a test
system which was running a beta BIOS. This BIOS bug has been fixed now.
