A few options:

1. Did you try nohup "halt -p &> /dev/null &" ?

2. You could start the halt in a screen session on the PIII and then 
   detach it.

3. My favourite: Setup a serial console and use minicom to halt the box.  
   This is doubly useful in that you'll only need to connect a 
   monitor/keyboard to the PIII if you want to access the BIOS.
