This used to be the case, but apparently is NOT a limitation of
the IDE interface itself.  On my Windows machine, I have the
latest/greatest Intel IDE driver for the Intel IDE interface in
my chipset.  It allows each device to run at the maximum speed
of the device, regardless if you mix fast/slow devices on the same
cable.

So the interesting question is what does the latest/greatest
FreeBSD IDE driver do when you mix fast/slow devices on the
same cable...  ;-)
