Because the virtio module id infrastructure is missing from the RHEL5.5 kernel,
an explicit MODULE_ALIAS() is needed to allow the module to be automatically
loaded.

This is specific to the RHEL5.5 as the module alias is extracted automatically
in upstream.

I've tested this against an SRPM from the RHEL5.5 beta and it fixes the module
autoloads properly with this patch applied.
