Fail to early boot with v2.6.27-rc2 to at least v2.6.29-rc2 due to dc1e35c

Hello,

My computer fails to make it past 'Unpacking kernel' with anything
later than dc1e35, to at least v2.6.29-rc2 due to dc1e35c, at least so
git bisect told me. While writing this bug I discovered I was using
gcc-4.1.1 when I thought I was using gcc-4.3.2; I upgraded, recompiled
2.6.28.1 and same results so I assume the same results would come from
me doing the 4 hour bisect again.

x86, xsave: enable xsave/xrstor on cpus with xsave support

Enables xsave/xrstor by turning on cr4.osxsave on cpu's which have
the xsave support. For now, features that OS supports/enabled are
FP and SSE.
