Yes we do.  See the v6 patches I've recently posted to various mailing
lists.

This patch series was created in the hope that it could be tested by a
sufficient number of people so that it could go into -rc1 as at the
moment, omap2plus_defconfig builds data-corrupting kernels.

Unfortunately, the response was not as good as I was hoping - it's
possible to count the number of testers on one hand.  So it's now
scheduled for the next merge window.  What this means is that v2.6.37
and v2.6.38 omap2plus_defconfig kernels _will_ _be_ _unsafe_ when run
on SMP hardware, and will remain that way.  If a fix is not suitable for
-rc, it most certainly isn't suitable for -stable.

What the patch set does demonstrate that we can know at preprocessor
time that plain v6 processors should be supported along side v6k and
v7.
