Yes it can. See attached patch below.

If it's not a problem, we can add the macro first and then work on
making it a sysctl. FWIW, it may also be nice to have a different
sysctl for each ata device, or something that can be tuned per bus or
per-device with atacontrol.
The patch attached below is what we need to make this a compile-time
option for kernel config files. It's small enough that I think we can
commit this now, and work on the sysctl/atacontrol tunable in the
meantime.
