I haven't yet tried reseating anything as that would require major
disassembly of the case. MacOS 9 and Linux both worked fine, though.

I just tried zapping the PRAM and now I get a lot of 
"RESETing SCSI bus" before and during the boot process. Sometimes it'll
appear thre or four times in a row, and I can hear the HD click each
time. I plugged in an older HD I know works and it also displayed a lot
of the reset messages.

I did get it to boot into NetBSD with the serial console -once-, but
only when the card was plugged in. Somehow, the video seems to affect
whether or not anything boots. Here is the error:

[...]

Thanks.
