That sounds very likely.

I'm at Debconf and building kernels and rebooting my machine is quite
disruptive.  When I'm back home I'll have a spare laptop I could try
this out on; that would be over a week from now at the earliest.

(Also please would you point me at the right instructions for trying
such a thing?  I can get the kernel source package and patch it but it
wants to build a lot of flavours so the build is very slow, and
nowadays I suspect I may have some kind of restricted boot problem?)

My experience with Linux upstream hasn't always been great but I can
give it a go.  Am I just to post to lmkl, or what ?
