Followup on Ubuntu/SATA issues

I promised to inform the world if I solved my Ubuntu problems using a PCI-SATA adapter and my old SATA disk (My PCI-SATA ubuntu misadventures).

Unfortunately, I haven't. Even using the SATA disk *not* as the boot disk, any significant I/O causes the whole system to freeze - no Ctl-Alt-Backspace or Ctl-Alt-Delete response. So it seems the mundane is true: Ubuntu really doesn't support my hardware.

I've upgraded to 8.04 on my laptop, though, and will soon follow suite on that desktop machine. Maybe I'll be in luck.
