This patch relaxes the default SCSI DMA alignment from 512 bytes to 4
bytes. I remember from previous discussions that usb and firewire have
sector size alignment requirements, so I upped their alignments in the
respective slave allocs.

No, FireWire only requires 4 bytes alignment.
I will channel a reversion of the firewire and ieee1394 hunks through
linux1394-2.6.git for 2.6.26.
Don't revert, just put the numbers down to 4 (just in case someone
decides to lower the default SCSI alignment down from four ...).
