I don't see a problem, because...

you are using the wrong resolution.  Windows uses 96dpi by default,
and 8pt at 96dpi is available in `sserife.fon'.

Note that in FreeType the various sizes available in `sserife.fon' are
not handled as bitmap strikes of a single face but have to be accessed
with different font indices.
