Re (1): I remember from helping someone with Mandriva and grub2 that
the problem is that Mandriva prepends its kernel and initrd stanzas
with (hdX,Y). Somehow (I've never looked at the scripts *that*
carefully), os-prober picks these up and, since the partition
numbering has changed between grub1 and grub2, the Mandriva stanza
fails.
Re (2): You can chainload but you can also load BSD kernels directly.
You just have to use 40_custom.
