x86: Disable HPET MSI on ATI SB700/SB800
HPET MSI on platforms with ATI SB700/SB800 as they seem to have some
side-effects on floppy DMA. Do not use HPET MSI on such platforms.
Original problem report from Mark Hounschell
http://lkml.indiana.edu/hypermail/linux/kernel/0912.2/01118.html
[ This patch needs to go to stable as well. But, there are some
conflicts that prevents the patch from going as is. I can
rebase/resubmit to stable once the patch goes upstream.
hpa: still Cc:'ing stable@ as an FYI. ]
