Looking inside of GENERIC, I found:
    #wd* at umass?
So, I'm uncommented it and compiled and installed a new kernel.

Side question: Why would "wd* at ummass" be commented? All the other 
lines for umass are uncommented.

After rebooting with the drive attached, the result was the same: 
"Device not configured" for any mount attempts on wd1. Further, 
disklabel got the same thing.

Is there something else in GENERIC I need to uncomment to make this work?
