We haven't yet tested the whole range of possible guests and I haven't
personally tried Windows 7 with new qemu+SeaBIOS.

The Wikipage suggests that the issue is related to the ACPI tables and
under Xen these are the same as those used by old qemu+ROMBIOS so it may
not be the exact same issue. Have you tried the same OS under old qemu?
(although I'm sure we would know already if Windows 7 support was broken
in xen-unstable...)

The screenshot would probably be useful to see.

Ian.
