On one hand, they don't -- the drivers I've updated in 2.6.27 aren't the
ones they need to boot. I deliberately left drivers/net and drivers/scsi
till later. I don't _expect_ any problems, but there's no rush -- we can
iron out any kinks with the drivers I've done already, then merge the
remaining updates into 2.6.28.

One the other hand, they _do_ need to fix such breakage immediately, if
they have it -- because what I'm doing here is nothing new. Most modern
drivers use request_firmware() already.

So if your userspace has this hypothetical "firmware-related breakage"
of which you speak, then it already won't boot on machines with qla2xxx,
which was converted to use request_firmware() in 2005. To pick but one
example out of many.
