I'd love to, but the link seems to be broken :-/

on the other hand the sil1178 datasheet link worked which also has the same
vendor/device/revision values (does sil use any other ids at all?), and judging
from the FRQ_HIGH read-only reg, it looks definitely as if it's not a sil164
but some of its dual-link capable cousins...

it would be interesting to compare the sil1162 reset values for the registers,
as those I get right now right after waking up again, match almost those of
sil1178 but not exactly... (it's just a matter of two registers where one bit
doesn't match the expected value...)
