 I've partioned and labeled the disk with sysinstall(8) from
8.2-RELEASE media.  Does 9.0 use different disk geometry cal-
culation than 8.2 or is usage of gmirror the culprit?  Both
8.2 and 9.0 kernels report the disk having 490350672 sectors.

 I think I'd rather reinstall 9.0 from scratch, getting rid
of MBR/disklabel as well.
