I guess you want to use the new features of 2.0? I believe it should
work to...

1) Put the disklabel back the way it is above, and

2) make MBR partition 0 start at 129024 with size 312452784, and make
it active. (If there's an MBR partition in one of the other slots for
wd0e, you can leave it, for now.)

3) Next, you'll need to label the disk as if it were new, using the
previously saved text label, as there will be no label in the (new)
primary NetBSD partition.

4) Now, assuming this is raid0, "raidctl -A root raid0".
("/etc/raid0.conf" will give an "already configured" error
on next boot, but you can move that out of the way later.)

5) Now, install the bootblocks to "/dev/rwd0a", copy "boot" to root,
and reboot.

There really isn't a file system on "wd0a"; there's a RAID set. The
filesytem starts further in. Nonetheless, it "just works" if you
install the boot blocks to a raid set configured as "root on RAID".
