after a week of fighting with an atom with ich7r sata in
ide mode, i finally found the secret sauce that keeps it
from "hanging."  i pushed out a changed
quanstro/9load-e820 and quanstro/sd which boot on my
atom machine in ide mode without causing interrupt storms.
other changes were included work around ahci power quirks
for this chipset, if your bios supports it, i would recommend
ahci mode.  i also pushed out a version of ether8169 as
quanstro/8169 that supports the particular 8169 macs that
are in my atom machine (and jumbo frames).

i have a feeling that these changes may be helpful in
correcting other intel ich-based ide problems.  i've got
an intel ich6-based machine that has exhibited similar
symptoms at work that i hope to test tomorrow.

i'll be interested to hear if these changes work for
other people.
