I have the same motherboard, but no SATA drives. I use the pata_via driver for
a couple of months now and experienced no problems so far. now running
2.6.19-rc6-mm2

1 Maxtor 6Y080P0 on primary IDE and 2 optical drives on secundary IDE (DVD-RW
master, CD-RW slave). all are connected with 80pin cables:
libata version 2.00 loaded.
pata_via 0000:00:0f.1: version 0.2.0
ata1: PATA max UDMA/133 cmd 0x1F0 ctl 0x3F6 bmdma 0xFC00 irq 14
ata2: PATA max UDMA/133 cmd 0x170 ctl 0x376 bmdma 0xFC08 irq 15
scsi0 : pata_via
ata1.00: ATA-7, max UDMA/133, 160086528 sectors: LBA
ata1.00: ata1: dev 0 multi count 16
ata1.00: configured for UDMA/133
scsi1 : pata_via
ata2.00: ATAPI, max UDMA/66
ata2.01: ATAPI, max UDMA/33
ata2.00: configured for UDMA/66
ata2.01: configured for UDMA/33
so as you can see, 80pin cable detection works for me.
