To be fair, we keep on actually running into things that _can't_ be
backported, like fibrechannel drivers that were written to take
advantage of changes in the SCSI support in 2.6.
This sort of thing will be particularly problematic with Opteron,
where the porting efforts for AMD64 have taken place alongside the
creation of 2.6.
