We had it, and we dropped it. :)
Writing a SeaBIOS driver is very easy, and the biggest limitation of
pvscsi is that it doesn't support the VMware option ROM. There is a
simple interface using only I/O BARs, or so I was told, exactly for the
purpose of booting---but we do not implement that interface. I'm not
sure how hard it would be to reverse engineere it, I do not have access
to vSphere.
