Since Sil3124 has better PCI read/write performance, as a reference,

Are you sure the values used are not the power on ones in this case ?
The values used, most likely, are BIOS-programmed.
sata_sil24.c does not call pci_set_mwi(), which is the only code in the
kernel (besides driver-specific, hand-coded stuff) that adjusts the PCI
cacheline register value.
