SATA support for the ServerWorks HT1000 chipset is bad/lacking in
FreeBSD-7.x, causing data corruption when disks are used in ATA mode.
Boxes using this chipset (like the Dell PowerEdge SC1435) cannot boot
FreeBSD-7.0 nor the latest 7.1-BETA.

I have tested the patch available at
http://www.freebsd.org/~jhb/patches/ata_ht1000.patch
to replace the GENERIC kernel in the 7.1-BETA ISO and was able to
boot/install and successfully use this patched 7.1 on my Dell
PowerEdge.
(See: http://lists.freebsd.org/pipermail/freebsd-stable/2008-October/045923.html)

The box is now running Apache/MySQL succesfully; and I have
successfully rebuilt world/kernel (RELENG_7 + ata_ht1000 patch) in
this box.

It would be a good idea to have this patch included in the next
7.1-BETA or RELEASE CANDIDATE, for widespread testing.

Otherwise, we would be accumulating two releases with bad or no
support for this chipset!
(kern/119851 shows another user just bitten by the same bug)

PS: I am sending this PR again (sorry of CCed parties get the same
message again) because the original PR never arrived at freebsd.org.
