SubjectNew via82cxxx.c - still not working here

I've tried to boot 2.4.0-test9-pre2 yesterday and it halted at the point
where it tried to read the paratition table, outputing all sorts of
errors (SeekError, IIRC). So I replaced via82cxxx.c with the older
version from test6 and now it's working.
Here is what I see with the old via82cxxx.c:
