been there, done that.  about two weeks ago, in fact.  :)

run fdisk -i on that disk and tell it no, you don't want the change
what the bios thinks, and then, for each partition:

 * yes, you want to change the partition
 * just keep all the defaults (fdisk will recalculate cyl/head/sector for you)
 * no, you don't want to explicitly specify beg/end address
 * yes, this entry is okay

then, tell it yes, write the new partition table.  doing this made the
netbsd boot selector work like a charm for me.

i think Manuel Bouyer <bouyer@antioche.lip6.fr> was the first to
suggest this to me.
