Hello Alan,
in the meantime I tried the kernels 2.6.23.1 as well as 2.6.24-rc2. Both show the same behaviour when using libata with AMD/NVIDIA PATA support: GPCMD_SET_STREAMING via SG_IO doesn't have any effect. With these two kernels I didn't try the "old" ATA driver - but I assume it would've worked out (changing your system from ATA to libata and vice versa turned out to be quite time consuming ;)).
