Sili/achi and Silicon Image 3512 chip

[Dennis Melentyev <dennis.melentyev@xxxxxxxxx>]

HI!

I am considering to do another update to 2.3-DEV soon after Matt done
with achi/sili tests and HAMMER V2 marked as stable.

My 320Gb Seagate ST3300831AS 3.01 SATA drive is connected via:
atapci0: <SiI 3512 SATA150 controller> port
0xdf90-0xdf9f,0xdfe0-0xdfe3,0xdfa8-0xdfaf,0xdfe4-0xdfe7,0xdff0-0xdff7
mem 0xfeaffc00-0xfeaffdff irq 6 at device 12.0 on pci2

Are there any possibility to benefit from switching to achi or sili
driver for it?
Is it supported by any of these drivers?
Is it ok to change access mode in BIOS from compatibility to ACHI?
Will I need any re-partitioning of drive or something?
