Okay, would you see any other reason why my root filesystem would
completely blow up after swapon /dev/hdb2 when /dev/hdb no longer exists?

All I did was remove /dev/hdb and forget to take the swap entry out of
/etc/fstab. On boot I got "attempt to access beyond end of device"
messages looping endlessly. I tried once with / mounted rw (it looks
like Debian still has / mounted ro when it turns on swap), and lots of
filesystem corruption resulted.
