pv-on-hvm drivers: build fixes for Linux 2.6.27+

Make the drivers build properly in a 2.6.27 environment as well as
against a kernel with pv-ops Xen configured on (in the latter case
more work would be needed to also make the drivers work, as there's a
large number of duplicate exports).

Portions from Charles Arnold <carnold@novell.com>.
