Directly in simple (with my entry added), it works. It also works 
directly from the boot: line.

Except that I have at least 80 variants of machines here. Our hardware 
department intentionally makes certain each motherboard is as different 
as possible.

The systems in question and both recent Intel. Here are the general specs:

Generic i915
Intel P4 2.66
1 GB RAM
nVidia GeForce 6200
SiI 3114 SATA
Intel HDAudio

Dell Dimension E510
Intel P4 3.2 EM64T
1 GB RAM
Intel Video i945 G/G2
ICH7 SATA
Intel HDAudio
ATI TV Tuner

So, it's interesting because they are both Intel systems, both 9x5. One 
is ICH6 and the other is ICH7. Otherwise fairly different hardware. 
Incidentally, likely drastically different BIOS, since Dell always uses 
their own stuff.
