When I said "lower due to broken hw" I was more thinking about things like the SiIimage driver, which actually limits the rqsize to 15 sectors due to some strange hw interactions with seagate SATA devices. (It will then raise it back up to 128 if it's not a Seagate SATA drive. I forget what the exact issue was. Some strange corruption in some limited case, and not allowing big requests worked around it. There's some strange IDE quirks out there...).
