Good catch - yes, that works fine. fdisk is now much more sensible:

Disk: /dev/rwd3d
NetBSD disklabel disk geometry:
cylinders: 2907021, heads: 16, sectors/track: 63 (1008 sectors/cylinder)
total sectors: 2930277168

BIOS disk geometry:
cylinders: 1024, heads: 240, sectors/track: 63 (15120 sectors/cylinder)
total sectors: 2930275055

Partition table:
0: <UNUSED>
1: NetBSD (sysid 169)
    start 63, size 2930274992 (1430798 MB, Cyls 0-193801/62/29), Active
2: <UNUSED>
3: <UNUSED>
Bootselector disabled.
First active partition: 1

I've not tested that this makes the disk bootable and I'm going to 
struggle to do so before RC4 is cut, but it seems that this should be 
committed and pulled up to netbsd-5 (I can do that if you want). If I find 
time, I'll track down the similar issues in sysinst, but they'll probably 
have to wait for 5.1.
