What version of Xen is this? ("xm info" should give version number at
least). 

Setting FFXSR (0x4000) is probably not "permitted", which also gives me
the indication that this is a AMD platform. Although, I guess setting
that bit shouldn't actually cause a problem as such. 

It's much more likely that the problem is that you're using pre-3.0.4
version of Xen. Try 3.0.4-1.

Probably same problem as above, try later version of Xen. The error
message about setting FFXSR isn't going to happen on a 32-bit Widnows,
as the 32-bit version of Windows doesn't use FXSAVE/FXRESTORE in kernel
mode anyways (unless the code specifically asks - but that's relatively
rare, so the saving by doing the "fast" version is minimal).
