I think the only change that interacts with the rest of the kernel was the 
one to add support for timecounters.  The rest should backport to older 
versions fairly easily.  My reason for not requesting pullups is that the 
changes are fairly disruptive within the WD33C93 driver, and I don't trust 
them not to fail where the old code accidentally worked.

That was just to force sync negotiation on my rather strange Fujitsu disk 
-- it won't do anything on other disks.
