It may not be related to ATA. I just reloaded into 2.6.17-mm6 to get the info
for Alan and saw it when booting up on that too:

PCI: Setting latency timer of device 0000:00:1d.7 to 64
ehci_hcd 0000:00:1d.7: EHCI Host Controller
ehci_hcd 0000:00:1d.7: new USB bus registered, assigned bus number 1
Losing some ticks... checking if CPU frequency changed.
ehci_hcd 0000:00:1d.7: debug port 1
PCI: cache line size of 128 is not supported by device 0000:00:1d.7

Note it was in a different place in here than in -rc1-mm1 (slightly later in the
bootup).

I'm fairly sure it's not new to this release.
