[gentoo-user] PATA in gentoo-sources-2.6.26-r3

[Thanasis]

Yesterday, I tried upgrading from gentoo-sources-2.6.25-r9 to 2.6.26-r3, 
but the new kernel can not mount the root filesystem, because it's on a 
RAID1 on an SIL680 controller.
In the previous kernel I had  CONFIG_PATA_SIL680=y , but in the new 
.config I cannot find any PATA.

# grep -i pata .config
(gives nothing)
Has it been removed from the newer kernels?
