Initial report....
I just installed my new IBM Ultra66 22GB drive and a Promise Ultra66 controller. The machine is an older Pentium 120, 64MB ram with i430FX chipset.
I applied your patch and rebooted...

My hdparm -Tt numbers improved quite a bit...
Before my new IBM drive was slave to my samsung drive on the motherboard ide controller.
The numbers were this:
Timing buffer-cache reads: 128 MB in 4.35 seconds = 29.40 MB/sec Timing buffered disk reads: 64 MB in 18.44 seconds = 3.47 MB/sec
And after moving the IBM drive to the Promise Ultra66 controller and using an Ultra66 cable the numbers look like this:
Timing buffer-cache reads: 128 MB in 4.21 seconds =30.40 MB/sec Timing buffered disk reads: 64 MB in 5.24 seconds =12.21 MB/sec
In what other ways can I test / stress test this new code? I'm going to setup nfs and samba going to that drive and pound on it.
