What is the status of this patch?

Jeff merged it in netdev-2.6#upstream so it is queued for 2.6.25.

The e100 driver broke in 2.6.25 on the ixp4xx based platform I'm using.
This patch seems to be the cause.

It appears to work again with pci_dma_sync_single_for_device() restored.
So I'm wondering if the patch below would be valid and correct?
