The latest kernel I got to work with a promise card (20268 - shouldn't be too much
difference to 20269) is 2.4.21pre4ac7 with hedrick's 2.4.21-pre4-2420ide-1 IDE port.
Re. performance on PC164LX: I guess the mobo itself is the bottleneck..

I have a Promise card and a couple of WD 180G drives. I have had a
number of problems with the card/drive combinations.

the 2.4.9 kernel seemed to work well but could not handle the larger
drives. the 2.4.19 kernels will handle the larger drives but seems flaky.
I personally believe that it is a kernel issue since I have a few
systems with modern IDE drives and newer kernels all of them seem to be
giving me heartache.

I have a system that has IDE drives connected to IDE -> SCSI converters.
I have 6 of these in a system as a raid 1 array. They seem to be working
well.
I am starting to think I should take my IDE interfaces and put them out
with the firewood to be burned when the house gets cold.
