I didn't find this config option but most probably because I remove IDE support from my kernel to test this libata?
mmm btw, I still have to check how to access my floppy with libata?

that said as far as:
# dmesg
[snip]
ata_piix 0000:00:07.1: version 2.00ac7
ata1: PATA max UDMA/33 cmd 0x1F0 ctl 0x3F6 bmdma 0xF000 irq 14
ata2: PATA max UDMA/33 cmd 0x170 ctl 0x376 bmdma 0xF008 irq 15
scsi3 : ata_piix
[snip]
(sorry, it seems that I forgot to copy it)

it make sense to me to limit to this bus capability?
