'dmesg' will tell you whether any wedges were found... If you've  
edited the gpt partitions, then you need to either reboot to get the  
kernel to find the wedges or add them manually.  I had little luck  
getting that to work and found that a reboot is prudent before trying  
to fdisk... You've probably already done that  however in which case I  
don't have any additional insight to offer...

I've modified that page extensively while in the process of installing  
5.0 on my Mac-Mini which I did several times so the information should  
be relatively current.

If you don't see something that looks like this in your dmesg, then  
you need to step back:

dk0 at wd0: EFI System Partition
dk0: 409600 blocks at 40, type: msdos
dk1 at wd0: OSX
dk1: 16708096 blocks at 409640, type: hfs
dk2 at wd0: NetBSD-root
dk2: 129183719 blocks at 17117736, type: ffs
dk3 at wd0: NetBSD-swap
dk3: 10000000 blocks at 146301455, type: swap

The kernel I'm running is:

NetBSD foo 5.0.1 NetBSD 5.0.1 (GENERIC) #0: Thu Jul 30 01:39:11 UTC
