For what it's worth, the Crynwr packet drivers for DOS use an inb from
the keyboard controller to establish a reasonably constant delay.  I
gather this is because the keyboard controller runs at something like 7
MHz on virtually every motherboard.  It runs at a higher clock rate on
PS/2s, but apparently it's reliable on ISA, EISA, and ISA/PCI
motherboards.

Sorry about such sketchy second-hand info, but maybe it's worth
something if you want to find a constant delay.
