Greetings all,

I've made some patches to 3.8-current to add pcidevs and pciide DMA
recognition for the Via k8m800/vt8251 chipsets (specifically on an Asus
a8v-mx board running openbsd/amd64). I was able to install from a current
snapshot without the patches, but now SATA drives are working in UDMA mode
5. Attached are the unified diffs to today's CVS and a dmesg.
